System locks up during multiple Podcast downloads

I am using the latest 7.7 (43) iTunes and found that when I download Podcasts using the setting "Allow simultaneous downloads" my entire system totally locks up after about 1/2 hr. It's not just the Beachball effect but the whole computer just freezes up requiring I turn the computer off. A massive crash.
I have been doing some testing and utility cleaning and it seems it is pointing to that exact setting causing the freeze. It doesn't matter what Podcast I select. It only matters when there are several episodes to download for any one given Podcast and I enable that setting.
My computer never locked up before doing this with earlier versions of iTunes.
Anyone else run in to that situation?

First guess, since your fan revs up.
Check your System Preferences>Energy Saver and make sure your slider for "put computer to sleep..." is on never and that you have unchecked the box next to "put the hard disk to sleep when possible"

Error 8104 During a Podcast download

What does error 8104 mean?

To view videos, you need at least OS X 10.3.9 and QuickTime 7.0.4.
Your computer probably meets the requirements, but not the OS.
Look here for the minimum requirements:

Transaction Locking during multiple Webservice - persistent webs sessions

Hi All, 
 
Yesterday evening we had a discussion concerning ESA architecture. We want to create (web)services for accessing the SAP business objects (using XI) and use these (web)services via visual composer, webdynpro or custom java development. 
 
It does not seem a big problem to perform creations and reads of transaction, but when we want to change objects, we saw some problems concerning locking/commiting and rollbacks. 
 
From our GUI we would like to be able to go in edit mode and from that moment on, the transaction should be locked. We then want to change certain parameters and commit only when we push the save button. 
 
We can invoke a webservice wich tries to lock the transaction, but at the moment the XI scenario is completed (=the lock is created), the program at SAP side (=proxy in our case) is also finished and the lock is automaticly removed. How can we do locking, when using webservices via XI? 
 
The problem of the rollback and commit we can partially solve by putting more logic in the GUI, but we don't want to do that. How can we do a change of a business object and remember this change without doing a commit on the SAP system.... . Same problem for the rollback. 
 
Is there a away to keep a session "alive" during multiple webservice calls or to simulate it? Every webservice invokation happens in a different context...isn't it? 
 
 
Just to make it a bit more clear. 
 
Suppose we create 6 service related to the business object bupa (business partner). 
- read 
- change 
- commit 
- rollback 
- lock 
- unlock. 
 
We create a GUI which uses these services. 
 
Step1: we want to see bupa in detail, so the read webservice is called and the retrieved details are shown in the GUI 
Step2: we want to go in edit mode, so the lock webservice is called to lock the bupa. The bupa should stay locked, untill the unlock is called. Here occurs the problem. The webservice lock is called, XI will trigger the proxy on the SAP system. This proxy will lock the bupa. As soon as the proxy-program is completed, the bupa lock will automaticly be removed ... . We want to keep this lock! 
Step3: we change the bupa using the change webservice. Only the user who locked the bupa should be able to change it. 
Problem concerning the locking occurs: standard we don't know who locked the bupa (this is done by the generic RFC user, configured in sm59). Should we pass some kind of GUID towards the proxy and build some additional logic to know which end-user in fact locked it... . Using the userid isn't sufficient, because a user could logon multiple time simultanously. 
 
Another problem is that we want to change the bupa, without having to do a commit yet.De commit should be called only when pushing the save button. When the proxy is ended and we did not do a commit, the changes are lost normally ... . 
 
What we in fact want to do is Simulate the bsp behaviour. 
Step4:We want to perform a save of the things we changed or a reset. This means the commit or rollback webservice is called. 
Step5: We want to unlock the bupa by calling the unlock webservice. 
 
 
Please give me your comments. 
 
Kind regards 
Joris

There are multiple strategies how to resolve this. They require that the last change time is available in the changed object, and also that the client keeps the value of the change time when it read the data.
1. First one wins
Immediately before posting the changes, the current change time is read from the server. In case it is different from the client buffer, then the client changes are discarted.
Example:
1. Client A reads data
2. Client B reads data
3. Client B changes its buffer
4. Client B checks if server change time has changed (result is no)
5. Client B writes his changes to the server
6. Client A changes its buffer
7. Client A checks if server change time has changed (result is yes)
8. Client A discarts its changes
2. Last one wins
Easy. Client just writes his changes to the server, overwriting any changes that might have occured since it read the data.
Example:
1. Client A reads data
2. Client B reads data
3. Client B changes its buffer
4. Client B writes his changes to the server
5. Client A changes its buffer
6. Client A writes its changes to the server -> changes from client B are lost
3. Everybody wins
Most complicated. In case of concurrent changes, the client is responsible for merging his changes with the changes from other clients and to resolve any conflicts.
Example:
1. Client A reads data
2. Client B reads data
3. Client B changes its buffer
4. Client B checks if server change time has changed (result is no)
5. Client B writes his changes to the server
6. Client A changes its buffer
7. Client A checks if server change time has changed (result is yes)
8. Client A merges its changes with changes from client B
9. Client A writes his changes to the server
"Last one wins" is definitely not water-proof. But even with the other strategies, data can potentially get lost in the short timeframe when the change time is checked and the actual update.
To make it more secure, server support is required. E.g. the client could pass the change time from its read access to the server. The server can then reliably reject the update if the change data has been updated in beetween by another client.

System Error occured during lock management in activating BI Content.

In trying to activate BI content, 'InfoObject Actual for Netweaver Demo', on clicking install after selecting the grouping settings, i get the error message
"System error occurred during lock management"
What causes this problem and how do i successfully install BI content?. Please assist.

Hi,
The error indicates missing or inactive message/enqueue server or network problems.
Please follow the steps below to help troubleshoot the problem
1. Logon to each server separately and goto SM12->Extras->Diagnostics to test the connections for the enqueue server. This will test the access of each server.
2 Use SMGW and SM59 to test the RFC connections. See SAP Note 47682.
You may want to have your network administrator/Basis people test the connections & analyse the network.
Use the message server/logon group testing tool "lgtst" (Note 64015), & the "niping" program (Note 500235) to diagnose the network.
Have a look at attached note 124562 in order to check if you have a hostname resolution problem.
Check your DNS / network setting that this kind of problems can not lead to blocking situations of the dispatcher.
To avoid the blocking of the dispatcher you can set the parameter
rdisp/reverse_name_lookup = 0 to avoid such situations.
Best of luck.
Rgds,
Colum

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.

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 ?

ITunes is locking up during sync of iphone and ipad during backup

When I try to sync either my iPad or my iPhone 3GS, iTunes is locking up during the backup stage of the sync. This started two days ago.

Thanks whatheck, that worked! I confirm that my antivirus (ESET Smart Security) was interfeering:
I disabled ESET and synched - it worked!
Then I also backed it up manually, and that worked also (30 seconds).
Then I re-enabled Eset and backed up again... it still worked...
BUT then I Synched again, and it failed! Had to kill iTunes and the applemobiledeviceservice with taskmgr.
So I turned off realtime file system protection in Eset, and after restarting iTunes (with 3gs still connected), Itunes said "Verifying PaulW's iPhone" for a couple minutes.
- Then it synched fine (couple minutes at most - got a new podcast).
- Then I backed up again manually which worked (10 seconds!).
- Then I synched again, no problem.
Note that AppleMobileDeviceService.exe is still using 50% cpu when sitting there doing nothing, even with iphone not connected. Have to kill it manually (in task manager - processes) or cpu fan runs constantly.
FYI: my ESET is a couple weeks out of date (subscription expired) will have to update it...

New homebuilt system lock ups.

So, I've asked this on a few other sites with no avail, so I thought I might as well try here.
Yesterday I helped my friend build a computer, and all went well until we tried installing Win7. The problem is the computer keeps locking up inconsistently. After running the installer a few times, it locked up anywhere from before the installer even begins to almost the end of the installer. Same issue with an Ubuntu live CD. It normally locks up sometime during the splash screen. When I force it to boot in text only mode, it usually can get to the desktop for a while before locking up. It's even locked up during a few of the bootable diagnostic tests I've tried.
So far, by testing these parts on different systems, I've eliminated the Harddrive, optical drive, and video card as possibly causing the lockup. I've run several tests off of the Ultimate boot CD. Memory test passed (though during it's 3rd pass it locked up). I've had the CPU running a floating-point stress test for an hour, and it hasn't hiccuped at all.
The only error message I've ever received from this thing is a "hypertransport sync flood" error. It's only come up twice out of the dozens of times it's locked up. I've heard that raising the RAM voltage can fix this, but I'm not sure how safe it is.
Any help or advice would be greatly appreciated.
Specs:
AMD PhenomII x3 740 Heka 3.0GHz
MSI 870-G45 (MS-7599)
Corsair 2x2GB DDR3 SDRAM 1333 (cm3x2g1333c9)
Rosewill RP600V2-S-SL 600W ATX12V v2.01
From my testing, the other parts should not be related to the crashing.

Ok sorry it helps when I read your entire post....
I know how to fix this
you will continue to keep getting this until you get all the microsoft updates , forget calling MSI or your chip set company they will not give you the answer you need , I have been there , they are no use for help with this issue
Go to MSI updater and Flash the Bios it is easy to do just follow the steps, you dont need to be an expert to do this windows will do it for you.
Then continue to keep updating windows it will be a slow painful process but it will fix the issue. I have built several systems all with the same problem, it took me several months of reading post after post, until I figured it out on my own.

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).

Podcast Download Error -39

This has happened to me three times now. When I am in the middle of downloading a podcast, my computer has either frozen or lost internet connection, so the podcast download gets interrupted. Once I restart, or reconnect to the internet, and go back to the list of podcasts, the one I was downloading is grayed out. I push the "Get" button next it and I get this error message: 'There was a problem downloading (said podcast). An unknown error occurred (-39). Please check that the URL is correct and the connection to the network is active and try again.' I have tried resubscribing to the podcast and even reinstalling iTunes. I didn't know if maybe there was a partial file saved somewhere that is making iTunes think there's still a problem. I don't know where to look for that though. Anyone else had this problem before or know what I should do to fix it??

Okay, I had the exact same problem. I restarted by computer during the middle of a podcast download because my computer froze. In order to fix this, (I'm using a windows XP now):
1. Go to the start menu.
2. Click on search.
3. On the left menu, click on all files and folders.
4. Type the episode name of the podcast.
5. Results should come up.
6. Click on the folder that is named after the podcast episode.
7. Delete the two files located in the folder. (2 in my case, they were named download and something else I can't remember)
8. Retry your download.
9. There you go, you got your podcast!

ITunes 11 Podcasts downloading problem

I subscribe severall podcasts. There's one of them, I don't know why, at the office downloads very slowly. To get it to download quickly, I am always pausing and resming the download.
In iTunes 11 when I pause when resuming the status bar comes a little bit back (eg. when pause there's 660 kb's downloaded, when resuming it goes to 500 Kb's)!
The other strange thing is that it dowloads more than the size of the podcast file!
When listening This, it is always coming back and forward.
Does anyone have the same problem?
Please try to pause and resume a podcast download an see what happens.
Thanks,
Jorge

Similar problem with iTunes 11.0.1.12 on win7. The crash seems to occur during the "file processing" part of downloading. I've tried removing the download file from the iTunes folder - it doesn't help. Really frustrating problem. It doesn't generate any error message beyond itunes need to stop and searching for a solution (the "solution" to update iTunes is the PROBLEM - not a solution).
I've installed VLC to play the files but it isn't iTunes and it won't sync with my ipod so... Apple people - - can't you do some simple software??? Do you really have to head towards bankruptcy again????
Geesh the Google maps flap was bad enough!

IPhone locks up during update/sync

I have synched my prior iPhone for several months so everything was set up fine, but it no longer will allow downloads. Last week, I tried to download the update for iPhone, and it locked up. When I disconnected, the iPhone was ruined, would only accept a download, but then would not complete the download. I got a new iPhone. Now, I have reloaded from a backup, I have the latest version of iTunes, and when I tried to download the latest iPhone update FIVE hours ago, it looked like it was working, but iTunes and the phone are stuck in "Updating iPhone Software." I will have to disconnect again; I cannot stay connected indefinitely. The telephone support is not available (I don't know what their limited hours are), but when I called last Sunday with the same problem, they could only help me redownload iTunes - and that didn't fix my phone. Help!!

I just bought the iPhone and when I brought it home, my phone and computer both locked up during teh software update. I spent an hour on the phone with a very nice lady, but she couldn't help me. She transferred me to a product specialist, and through conversation, we realized that I was the problem. I had my phone plugged into a powered USB hub, and it just would not work that way. I figured that since the hub was 2.0 and was getting power from my outlet, it would be fine. Guess not... As soon as I plugged it directly into my computer USB port and reset everything, it worked fine. I think you said you were using a laptop to sync, so maybe your USB port is just not cutting it. Good luck w/ the fix.
