60d using built-in optical system "locks up" camera intermittently

I've been having an intermittent problem for a long time with my 60d "locking up" that seems to be getting worse. I'm using the built-in optical system in the 60D in E-TTL to fire a Speedlite 580EXii and a speedlite 580EX, both off camera, using the pop up flash to trigger them but setting it so that the pop up flash doesn't add any extra light to the exposure. It's just triggering the Speedlites, camera usually in manual mode but flashes in E-TTL.
I love this set up but the problem I have is that occasionally the camera will just lock up. I try to press the shutter halfway to focus and get nothing. The camera's still on but completely unresponsive. It's not the battery cycling, as I've checked that out, and I don't believe it's a low light focus issue, as I'll often point the camera right at a light when it does this hoping to get it to work again and usually it does nothing to help. The weird thing is that usually after a minute or two of fiddling around the pre-flash sensor will finally come alive and start doing it's thing again and I can finally fire off a shot again and it'll work till it locks up again the next time. It might happen four times during an hour of shooting. Sometimes turning the camera off and back on will clear it and sometime it doesn't but usually when it's locked up it'll stay like this for a couple minutes until finally it becomes responsive again. I know it sounds like a battery issue but I really don't think it is as I've swapped them out many times and still get the same problem.
I should point out I've had the same problem with two Rebels and now this 60d so I don't know if it's my gear or operator error or what. I know the wireless E-TTL system is complicated and doesn't always work but this problem is wildly frustrating and seems to be getting worse.
Has anyone else ever had a problem like this? I don't know if I should spring for the 600EX and the radio controller and if that might be better or not.
If anyone has any insights or has experienced this before I'd love to hear how you dealt with it....Thanks, Robert

If the "lock up" occurs sometime after taking a series of shots, I would venture to guess that it's the on-board flash shutting down temporarily to prevent overheating. After it cools off a bit, the camera returns to working normally.
When used for wireless off-camera communication with other flashes, the on-board flash fires a series of "pops", which can heat up the flash tube a lot if being used relatively continuously, eventually causing overheating and risking burning out the flash tube. I believe all the camera's are designed with some sort of sensor to stop the flash from firing when it starts to get overheated, rather than let it burn itself out. After the flash cools, it resets and allows the flash to work again.
I don't know if you can cause the on-board flash to shut down this way if it's simply being used as flash. It might not recycle fast enough to overheat. But I really don't know because I almost never use on-board flashes on any of my cameras that have them. The very short duration "bursts" used for off-camera flash communication, however, don't fully drain the flash's capacitor and cause it to slow down and recycle, the way using it as a regular flash will. So there is more risk of continuous usage causing overheating.
If it is due to overheating, the easiest solution is to get and use an ST-E2 module. That's an off-camera flash controller that sits in the camera's hot shoe and communicates via near IR light emissions, has a little better range, and will not overheat. It's less obnoxious than the on-board flash too.
The 600EX-RT is used with a different off-camera controller, the ST-E3-RT (or a second 600EX-RT). It cannot be controlled by the camera's on-board wireless system at all. But it would give considerably greater range in most situations and doesn't require a direct line-of-sight setup the way the optically triggered flashes do.

Using built in optical digital audio output for 5.1

So, lets say i want to mix something in 5.1 using logic or soundtrack pro, can i use the optical digital audio output of my macbook to send the signal to a home theather or something to mix it?, or i need a special hardware card for this?
Thanks a lot!!

Hi alece,
Just to clarify something;
When using an optical cable there are several standards of audio that can pass through the cable:
S/PDIF - a stereo signal - http://en.wikipedia.org/wiki/Spdif
AC3 or Dolby Digital - up to 5.1 surround - http://en.wikipedia.org/wiki/Ac3
Dolby Digital Plus - up to 7.1 surround - http://en.wikipedia.org/wiki/DolbyDigitalPlus
ADAT Optical - up to 8 channels of audio - http://en.wikipedia.org/wiki/ADAT_Lightpipe
MADI - up to 64 channels of audio - http://en.wikipedia.org/wiki/MADI
I´m sure other people can add more to the list if they want to, my point is that these signals can pass through the exact same kind of optical cable.
The important bit to know is what does your equipment and software support... in theory your question is quite logical, a software can play 5.1 surround to a optical output like Apple DVD Player does with the built-in sound card of a modern mac. However, Logic does not support live encoding of AC3. That is why you have to output the surround mix in Logic to a sound card with at least 6 channels (5+1 as in 5.1) connected to your speaker system. Typically this would be 5 active studio monitors plus a sub. If you were thinking to use an existing stereo I would not recommend it since most consumer speakers have no limiters to protect them from damage (but may be possible depending on your amplifiers inputs)
I hope this answered your question

After uploading file in BLOB using webutil file on system locked?

I uploaded file in BLOB using webutil upload utility. But after uploading it locks the file and i cannot delete the file unless i close the iexplorer window.
Is there any way to unlock the file and delete it with out closing the application(iexplorer). If any body knows please reply.

Can you use surround sound with the built-in optical out on dual 1.8 g5?

Ok here's the thing, I just got the new version of Final Cut Studio, and was wanting to set up my g5 to utilize the surround mixing capabilities of SoundTrack Pro 2.
I have verified that i'm getting 5.1 sound via Apple's DVD Player, but when i go to Applications-> Utilities->Audio MIDI Setup, I cannot configure the system for multiple channels. It only allows me to output stereo.
Is my assumption of being able to use the built-in optical out for 5.1 monitoring incorrect? Do I have to go buy a firewire/usb audio interface?
Info about my system:
I have a Bose Acoustimass 10 5.1 Speaker setup.
I have a Onkyo DR-C500 5.1 Receiver, which does dolby pro logic 2 and dts decoding.
The Onkyo Receiver is hooked up via the spdif optical output of my G5.
I have a Dual 1.8 G5 with this info about the Built In Sound Card:

Greetings and welcome to the Apple boards.
The Mac puts out encoded 5.1. It is the function of the amplifier, receiver or decoder to take that signal and turn it into something useful. At minimum you will need a device that can accept that output and turn it into something useful.
Most studios that I am familiar with want to be able to use their own 5.1 decoder, amp and speakers. Juicier sound!

Can I install a new operating system using a USB optical drive?

My Mac is out of date, I'm still running 10.5.8 but have the Snow Leopard disk to update my operating system to 10.6.3. However, my built-in optical drive is broken so I use a USB powered optical drive. So, when I start the process of installing the new operating software, will the MAC direct itself to my USB drive to boot when necessary?

Thanks for the replies. Just to clarify, because I'm on 10.5.8 I have to upgrade to Snow Leopard using a dvd disk, which I have. I cannot upgrade to any other more recent operating system until I'm on Snow Leopard, so that's the first thing to do.
So, just to clarify further, I have a DVD drive that plugs into 2 USB ports that I use to burn and read DVDs, ever since the inbuilt DVD drive on my iMac started sticking disks inside.
So...I'm really looking for the best way to do this upgrade with what I have...I don't know whether the Mac will find the disk if it is on the plugged in portable DVD drive rather than the inbuilt DVD drive....
Any advice greatly appreciated...

System lock ups when using hard disks

At first I thought I had the same issue as in this thread however after reading his logs I decided that it is unlikely since the topic opener seems to be getting a bunch of
Apr 4 17:00:15 daxteriv slim[708]: (Do:882): GLib-CRITICAL **: Source ID 46 was not found when attempting to remove it
, so I decided to start a new thread.
I am not getting anything in my logs when I look at them after the crashes. It seems as if whatever is causing the issue makes it impossible to write to the drives so nothing seems out of place until after it's too late, and quite obvious that something is wrong. The sole exception to this was some complaint about ata9.00, however this seems to have been a red haring since the complete removal of this drive solved nothing, though it did make the error go away.
I have run memtest, and prime95 (in windows since at the time I didn't want to boot my system) both coming back negative. I also checked for SMART errors, particularly UDMA errors. Again, negative.
Here are some previous threads of mine that I believe to be all related to the same issue:
https://bbs.archlinux.org/viewtopic.php?id=195449
https://bbs.archlinux.org/viewtopic.php?id=193937
https://bbs.archlinux.org/viewtopic.php?id=192704
[edit3] My previous thought was that this was a btrfs issue, however now I think it may be more hardware related.[/edit3]
Last night I was writing urandom to a new drive and I woke up in the morning to see that it had stopped prematurely, but not due to lack of space. The system had not locked up completely, which was new, however, as soon as I did something that accessed the disks (tried using the Gnome Dash), all hell broke loose. I immediately hit the power button, which would start a shutdown. I didn't know about REISUB, or I would have tried that. In anycase the shutdown failed and I had to hard reboot.
The evening before I was playing games just fine and doing normal activities.
Also, the other day, while booted into the live cd I think it started to crash since it was acting extremely bizarre, but I shutdown, successfully, before it could do more than complain a lot. At the time I was in the middle of scrubbing a btrfs volume after a system lock up. I think, but am not certain, that I saw on my motherboard "A5" which, according to the manual indicates "SCSI reset", but I had an extremely bad viewing angle. I know neither if what I think I saw was correct, nor do I know if the system was again in the process of a meltdown.
In general there is no activity that seems to be able to instantly trigger this, though in each case, if my memory serves me well, there was a constant stream of data either to or from a HDD.
My set up is that I have 5 HDDs, and an SSD. One HDD has Windows, my fallback installation of Arch, and daily backups. Another drive, which I just installed a few days ago currently only has single 50GB btrfs partition that is not part of any sort of larger volume. I also have three other drives each with four parttitions each involved in a btrfs volume. At the top is a 175 GB volume in a RAID0 configuration, after that is a 25GB partiton in RAID1, then a 650GB partion (RAID1), and the remainder of the disk (about 80GB) is in single. The RAID0 is has games on it and sometimes for short term storage (a few hours), the 25GBx3 RAID1 is used for Arch as well my ~/.local, ~/.cache, ~/.thunderbird, ~/.mozilla, and ~/.config. The 50GB partition I mentioned is currently doing the job of this volume, and was not mounted last night, but has been before. The 650GBx3 is used for long term storage of just about everything, in particular ~ is mounted here. The single configured volume is used for downloads, storing ISOs and installers. The SSD is used for caching those partitions used in the RAID0 volume with bcache. I DO NOT think this is a bcache issue since the RAID0 volume has never had any errors.
My motherboard is a ASUS X79-DELUXE which has the SATA controllers: Intel X79 Express Chipset, Marvell 9230, ASMedia 1061.
[edit] Oh, I'm on kernel 3.19.2 and btrfs is 3.19.
[edit2] Also, I converted the RAID0 to a single in case that matters.
[edit4] I finished scrubbing and copied my "journalctl -b" output to pastebin. I can't see any thing that might raise any flags. http://pastebin.com/WXpbpTuc

nstgc : it's hard to tell if your problems are memory related, but memtst often needs multiple passes to detect errors.
How many passes did you let it make ?
Is it possible for you to take out say half of the memory chips and see if that changes anything ?

Cross System Lock using for roles?

Hi everybody,
maybe one of you can support me or have some experiences in case of using the Cross System Lock. We are checking the possibilty to implement the Cross System Lock (using in ChaRM, Scenario E (/TMWFLOW/Config_Lock).
First of all, we made a successful test in usage of table content.
Example:
You save a table modification in a Transport Request generated in ChaRM. Thus, the Transport Request is buffered in a Change Document. The result is that the table modification is locked in the object-monitor (/TMWFLOW/LOCKMON).
However, you save a role (pfcg) in a Transport Request generated in ChaRM the included objects in this role are not buffered in the object-monitor (/TMWFLOW/LOCKMON)
Thanks for your answers!
Best regards
Joachim Eichner

If you use the report TMW_TRKORR_LOCK_UPDATE against the role transport after saving your changes in it, this will register the role objects in the CSOL.
The Role transport tool does not automatically trigger the FM that registers the objects in the CSOL, just like manually adding objects to a transport doesn't trigger it. Therefore the workaround is to run this report. Only the transport owner is allowed to run TMW_TRKORR_LOCK_UPDATE.
In our experience it is not that CSOL does not support roles and authorizations; for the purpose of retrofit, it is able to detect conflicts reliably if the report is run consistently after saving role changes to transport. If no conflicts exists, auto-import works fine. If conflicts exist, then roles must be manually retrofitted.

How do you Install Win XP using Boot Camp without use of an optical drive?

So I'm about at my wits end. I'm try to get Windows XP on my OS 10.5.5 MacBook Pro. I've run into what seems to be a bit of a dead in. Unfortunately my optical drive has gone stupid on me and won't allow me to get through the entire set-up. The Mac has know trouble seeing the Installation Disc. After my partition has been created and I click start Windows Installer, the computer reboots in a normal fashion up to when you get the apple with spinning progress wheel. At this point the screen goes black and I get a "-" blinking in the top right corner of the screen. I figure it's just trying to boot from Win Install disk but it just kinda sits there. So here's my question. Is there some way to boot this Windows Installation from anything else but the CD? I luckily have an image of the WinXP CD in about 5 formats. I'm going absolutely crazy because I had just Installed WinXP not more than an hour before I ran into this initial problem but wanted to change the WinXP partition to FAT 32 as opposed to the NTSC format I accidently used. I would really appriciate any help in my dark hour.

Kirkdan:
I really would like to help you and get your issue resolved in your dark hour as you said. I am afraid that I do not have good news for you. This is because the limitation put on by this entire process of installing Windows via boot camp.
The answer to you question to install windows from any other medium other than your built-in optical drive is a NO. This won't work since once Windows begins to install then it will not have all the drivers installed to recognize the external CD drive (USB/Firewire) and installation will halt.

Built In Optical Drive????

This may be a completely anal question but I have a 2008 Macbook Pro and am wondering does this laptop come with a built in optical drive. I am looking at partitioning 10GB to run Windows for a design program I have that is not Mac compatible and it says I need a built in optical drive....I would appreciate any answers as to where I can look, ect......Muchos Gracias

You can boot into one operating system or the other, but once in one you cannot simply switch to the other. To accomplish that you would need to use virtualization software that enables you to run Windows concurrently with OS X. See the following:
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
1. Install the Apple Boot Camp software. Purchase Windows XP w/Service Pak 2 or Vista. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
2. Parallels Desktop for Mac and Windows XP, Vista Business, or Vista Ultimate. Parallels is software virtualization that enables running Windows concurrently with OS X.
3. VM Fusionand Windows XP, Vista Business, or Vista Ultimate. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
4. CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
5. VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not yet fully developed for the Mac - some features are not yet implemented - but it does work otherwise.
6. Last is Q. Q is a freeware emulator that is compatible with Intel Macs. It is much slower than the virtualization software, Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system.
See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion.
Boot Camp is only available with Leopard. The Boot Camp Beta that was used with Tiger has expired and is no longer available for use. So contrary to the other poster's comment, Boot Camp isn't truly "free." You must purchase Leopard to get it.

Odd System Lock-Ups [XP-Pro SP3]

Something odd is happening, on my normally, and otherwise stable laptop with XP-Pro SP3.
I have observed that on Fridays, at about 11:30AM MST/USA, I get system lock-ups. Everything just freezes.
I have poured over Event Viewer, and nothing is getting launched at about that time. Really nothing in System, or Applications, from about boot-up, other than my Browser (Chrome). Not one Warning, or Error, and little real activity.
I cannot verify that this happens every Friday (do not remember it on Friday Jan. 13, for instance, but then the Adobe Forum Log-in went down), as I am often out of town. However, and based only on memory, this has now happened about 5 - 6 times, and always late in the morning, and on Fridays.
Normally, I only have my Browser open, though this time also had Windows Explorer minimized. During this AM, I had PrPro, PrE and Photoshop open at times, but none was open, when the lock-up happened.
I tend to suspect something is trying to update, but it's not showing in Event Viewer. A few times, there was a Norton Live Update Scan, but those were usually hours before. Those are not download/installs, as I have Live Update to full manual, and the same for all other such utilities.
Does anyone have any ideas, or perhaps a monitoring utility, that will gather data, better than Event Viewer?
TIA,
Hunt

hmm.... google.... i dont really trust google much....
i used to have something ( i use xp ) that basically I had total control over when to connect to isp etc and disconnect... but for life of me cant remember what it was. that was years ago.
now when i start computer it automatically ( partially this is due to isp of verizon ) connects and then gives me control of computer ( is part of boot and load process now ).
your prob seems to be some kinda scheduled thing is why i was thinking maybe turn stuff ' off ' that might be trying to update or something under the radar ( is part of the system more or less.. components ...)
this area
you wont see this related stuff in event viewer type listings ... and gets kinda complicated to me at least.

Verify Disk results, confusing.. Can they be the cause of system lock ups?

I have been experiencing strange freezes on my Mac Pro 2008 system.
My boot disk is a 50% full 128GB SSD from Crucial and is running beautifully fast however for the past couple of weeks my system often freezes for anything from 3 seconds to 30 seconds and then the Finder restarts.
After the Finder restarts everything continues running smoothly. As if nothing ever happend, no error reports, no apps crashed, nothing.
I have verified disk permissions and verified the disk itself in Disk Utility but I am not quite sure what these results mean and if they could be the cause of these random lock ups.
here are the results:

I would really appreciate it if someone that knows their way around this stuff could help me troubleshoot this.
As for the problem of the system locking up it does not happen in the same application consistently.
Often it happens in Firefox but it could equally often happen when working in Photoshop, browsing files in the Finder or trying to access the Spotlight search via the keyboard shortcut.
When the system locks up I get the spinning beach ball and I can still move the mouse and click and even still access CMD+TAB app switcher, switch spaces and all those things, just applications become non responsive.
If you need any more details please let me know.
Thanks for reading,
Jannis

These are innocuous errors that you may safely ignore. However the disk error is a problem. Do the following:
Repairing the Hard Drive
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger and Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.

Random system lock-up or freeze / Linux 3.4

Hi
My system seem to regularly lock-up in the linux 3.4[1] series. Whenever this happens, I had to power cycle the system by holding down the power button. Keyboard, numlock, mouse wouldn't work. I'm still looking-out for a pattern that trips this lock-up consistently. The lock-up doesn't happen for days and can happen every other day as well.
During this lock-up nothing gets captured in the system log too. I parsed 'journalctl -a'. Here is a sample from such a lock-up:
Jun 30 18:01:01 chaembian /usr/sbin/crond[4747]: pam_unix(crond:session): session opened for user root by (uid=0)
Jun 30 18:01:01 chaembian /USR/SBIN/CROND[4748]: (root) CMD (run-parts /etc/cron.hourly)
Jun 30 20:45:03 chaembian kernel: Initializing cgroup subsys cpuset
Jun 30 20:45:03 chaembian kernel: Initializing cgroup subsys cpu
I noticed the lock-up around 18:30 and instead of forcing it to shutdown, I thought I would give it sometime to snap out of it. But nothing happened until 20:45, when I forced the restart. The only other anomalies are (picking out their first apperances):
Jun 25 13:57:33 chaembian kernel: BUG: Bad rss-counter state mm:ffff880115e10a80 idx:1 val:-2
Jun 25 13:57:34 chaembian kernel: BUG: Bad rss-counter state mm:ffff880115e10a80 idx:2 val:2
during shutdown
and
Jun 10 10:08:57 chaembian kernel: r8169 0000:05:00.0: eth0: link down
Jun 10 10:08:57 chaembian kernel: r8169 0000:05:00.0: eth0: link down
Jun 10 10:08:57 chaembian kernel: NOHZ: local_softirq_pending 08
during boot[2]
I'm not sure if these precipitate the lock-ups but these are the things that stand out in the logs for my untrained eyes.
> uname -a
Linux chaembian 3.4.4-2-ARCH #1 SMP PREEMPT Sun Jun 24 18:59:47 CEST 2012 x86_64 GNU/Linux
Let me know if you require any more information.
1 - I was a regular -ck patched user. Since the time the series started serving 3.4 series, I was having lock-ups. Since the stock was still at 3.3 then, I was using the stock as I was trying understand the issue from the logs. But ever since stock moved into 3.4, the lock-ups are happening in this as well. Again, since I have not been able to recreate the issue on demand, I'm not able to attribute the regression to 3.4 conclusively.
2 - A similar issue that was reported from last year will be System lock-ups or software resets, with increased ethernet activity. But the key difference is that my logs have just one instance of this message generated at the time of boot.

Yes, that's how I have it setup. Until today's forced power cycling earlier today, the journal had all the entries from June 10th. The system gets proper shutdown daily (there is a power shortage where I live and to counter there is a scheduled, daily power shedding for 1 hour).

How do I use a NAS file system attached to my router to store iTunes purchases?

We have four Windows devices networked in our house. They all run iTunes with the same Apple ID so when any one of them has iTunes running, we can see that computer on our Apple TV. Two run Windows XP, one runs Vista Business, and the newest runs Windows 7. Upgrading all to the same Windows software is out of the question. Our NAS is hung on an "off warranty" Linksys E3000 router which communicates via USB with a 1TB NTFS formatted Western Digital hard drive. Our plan when we set up this little network, not cheaply, in our 1939 baloon construction tank of a house, was to build our library of digital images, music, and video primarily on that device. It supports a variant of Windows streaming support, but poorly. The best streaming support for our environment seems to be our ethernet connected Apple TV which is hung off the big TV in our family room, and has access to the surround sound "Home Theater" in that room. We've incrementally built up collections of photos, digitized music, and most recently educational materialsd, podcasts, etc. which threaten storage limits on a couple of default C: drives on these windows systems. iTunes, before the latest upgrades, gave us some feedback on the file system connections it established without going to the properties of the individual files, but the latest one has yet to be figured out. MP3's and photos behave fairly well, including the recently available connection between Adobe software and iTunes which magically appeared, allowing JPEG files indexed by Adobe Photoshop Elements running on the two fastest computers to show up under control on the Apple TV attached 56' Samsung screen!
Problems arose when we started trying to set things up so that purchases downloaded from the iTunes store ended up directly on the NAS, and when things downloaded to a specific iTunes library on one of the Windows boxes caused storage "issues" on that box. A bigger problem looming in the immediate future is the "housecleaning" effort which is part of my set of "new years resolutions." How do I get control of all of my collections and merge them on the NAS without duplicate files, or when, for example, we have .ACC and .MP3 versions, only the required "best" option for the specific piece of music becomes a candidate for streaming?
I envission this consolidation effort as a "once in a lifetime" effort. I'm 70, my wife is 68 and not as "technical" as I am, so documented procedures will be required.
I plan to keep this thread updated with progress and questions as this project proceeds. Links to "how to" experiences which are well documented, etc. may be appreciated by those who follow it. I plan to post progress reports and detailed issues going forward. Please help?

Step 1 - by trial and error...
So far, I have been able to create physical files containing MP3 and JPG on the NAS using the Windows XP systems to copy from shared locations on the Vista and Win7 boxes. This process has been aided by the use of a 600 GB SATA 2 capable hard drive enclosure. I first attach to Win 7 or Win Vista and reboot to see the local drive spaces formatted on the portable device. Then I copy files from the user's private directories to the public drive space. When the portable drive is wired to an XP box, I can use Windows to move the files from the portable device to the NAS without any of the more advanced file attributes being copied to the NAS. Once the files are on the NAS, I can add the new folder(s) to iTunes on any of the computers and voila, the data becomes sharable via iTunes. So far, this works for anything that I have completely purchased, or for MP3's I made from the AIC files created when I purchased alblums via iTunes.
I have three huge boxes full of vynl records I've accumulated. The ones that I've successfully digitized via a turntable attached to the sound card on one of my computers and third party software, have found their way to the NAS after being imported into iTunes and using it to bring down available album art work. In general I've been reasonably well pleased with the sound quality of digital MP3 files created this way, but the software I've been using sometimes has serious problems automatically separating individual songs from the album tracks and re-converting "one at a time" isn't very efficient.

Can I use another Mac's system restore disc on my Mac?

Q. Can I use the grey coloured System Restore discs that shipped with Mac A to install OS X onto Mac B?
A. In most cases, due to technical and licensing reasons, the answer is no. The answer is definitely no if any of the following apply:
Any part of the software on the system restore disc is currently installed or in use on Mac A, or on any other computer1
The OS on the disc is any version of Leopard (10.5.x), or is any version of Tiger later than 10.4.42
Either of the two Macs has an Intel processor3
The system restore discs from Mac A contain an older version of Mac OS X than the version of Mac OS X that was on the install discs that would have shipped with Mac B4
However, an installation attempt may be successful, and compliant with all OS X licensing terms, if all of the following conditions are met:
No part of the software on the system restore disc is currently installed or in use on Mac A, or on any other computer1
The OS on the disc is Tiger 10.4.3 or earlier, or is an earlier version of OS X (10.3.x, 10.2.x, etc)2
Both Mac A and Mac B have PowerPC processors (G3, G4, or G5)3
The system restore discs from Mac A contain a newer version of Mac OS X than the version of Mac OS X that was on the install discs that would have shipped with Mac B4
All terms of the Mac OS X Software License Agreement are followed, particularly sections 2 and 3 regarding permitted usage and transfer.
Even if all the above conditions are met, software restore discs contain computer-specific releases of Mac OS X, and may not install or work properly on a Mac that has a hardware configuration that is significantly different than the original.
Notes
The license agreement for single user copies of all versions of OS X, including all versions that ship on system restore discs, do not permit any part of the software to be installed or used on more than one computer at the same time.
The provision restricting the use of grey coloured system restore discs to the same Mac with which they shipped was introduced with the 10.4.4 Software License Agreement, and has been carried through to the 10.5 Leopard Software License Agreement. This restriction was not present in the Software License Agreement for earlier versions of Tiger, nor for earlier versions of Mac OS X.
All Macs with Intel processors shipped with a Mac OS X EULA restricting usage of the software restore discs to that Mac only. The license that shipped with G3, G4, or G5 Macs that shipped with 10.4.3 or earlier permit the transfer of OS X to another Mac, provided that all terms of the license agreement are followed. Furthermore, the architecture of PowerPC and Intel systems are incompatible enough that neither platform's system restore discs will install on the other.
Mac OS X system software will not properly run on, and may not even install on, any Mac that is newer than it, because the software lacks the hardware drivers to run properly on the newer hardware. Details are in this document: http://support.apple.com/kb/HT2186

Gray Install Discs are Machine specific, so even if both were Intel iMacs they'd have to be the same Models.
Leopard 10.5.x is another possible option besides Tiger/10.4.x.
Tiger Requirements...
To use Mac OS X 10.4 Tiger, your Macintosh needs:
* A PowerPC G3, G4, or G5 processor
* Built-in FireWire
* At least 256 MB of RAM (I recommend 1GB minimum)
* DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation
* At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools (I recommend 20GB minimum)
http://support.apple.com/kb/HT1514
See Tom's, (Texas Mac Man), great info on where/how to find/get Tiger...

Or Ali Brown's great info on where/how to find/get Tiger...
http://discussions.apple.com/thread.jspa?messageID=10381710#10381710
Leopard requirements/10.5.x...
* Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor
minimum system requirements
* 512MB of memory (I say 2GB at least)
* DVD drive for installation
* 9GB of available disk space (I say 30GB at least)
You have to call Apple & likely ask for a Product Specialist to get it, if they still have it!

System Lock Error while reset & reversing the cleared document - FBRA

Hi Experts,
Currently using t-code FBRA, when user trying to reset & reverse the cleared document , they are facing "System Lock Error". We have analyzed on this issue and found SAP note no. u201C487347 u2013FBRA: Overflow of the lock table in production systemu201D . After implementation of this note, SAP has created one new transaction code, FBRA_LOAC.
However, when we tried to reset & reverse the cleared document using t-code FBRA_LOAC, we face the same error.
Can you help me to resolve this issue ?
Thanks in advance.
Regards,
Manish

Hi:
We once faced these issue and got it resolved by extending parameter after extending the profile-parameter "enque/table_size", as per note note 13907. Do not forget the restart the server after extension.
Regards
