Fcpx background disk activity

        Just curious about what is going on after I open FCPx and can hear my external HD being accessed. The familiar sound of the external drive reading/writing (dunno) can be heard even when I am doing nothing and am working in another program.
       Ah....as quickly as I ask the question I realize what it is so I'll leave this here in the event somebody else asks a similar question.
      I quit FCPx and the disk activity stopped and then I realized it was probably background rendering. I booted FCPx turned background rendering off and the access stopped. Question asked and answered.

Hi, Was looking through the forum because of a similar issue that occured twice yesterday. I was cleaning up and consolidating my externally connected disks (too many backups) 1 x USB connected, a NAS store and my Airport time capsule.  After a long session of deleting files I got the spinning globe on the finder window, I could not access other apps to look at what was going on, but I could here the  Time Capsule rattling away. Left it for 20 mins still the same, so had to crash the system to recover (hold power button in).  Four hours later and more tidying up, went to shut down and again heard the Time capsule rattling away but this time I got to the white screen and the spinning circle. Twenty minutes later still not shutdown so another crash of the system.
I am not sure whether this problem is the same as you have described but there are similarities hence I thought I would post.
Hope we can find a resolution

  • Mountain Lion 10.8.2 Heavy background disk activity but not time machine

    Since accepting the Software update that puts my version of ML as 10.8.2 I have began to notice a regular (every hour) constant heavy activity in one of my drives (yet to identify which one).
    The said drive(s)?? whirr up and carry out activity that sounds as if it were carrying out a time machine backup BUT there is no indication that time machine is carrying out its job nor are any of the backups date/time stamped for the activity taking place.
    Any ideas as to what is happening would be greatly appreciated as it is becoming rather annoying to listen to heavy background activity without being able to identify what is happening.
    Thanks in advance

  • Disk Activity Problem w/ "update" Process

    I'm having problems with unusal spikes in disk activity which causes everything I'm doing to pause until the activity is finished. If I'm browsing or switching between folders the app and OS pauses, if I'm watching a video, the video will pause while the audio will continue for a second before stopping.
    My CPU, System Memory, and Disk Usage are all in a very low percentile of usage. There's no problem there.
    The culprit I've determined is a process called "update" (process ID 89, user: root) At regular intervals "update" will appear on the list of active processes and it is exactly then, everytime, that the system will pause. The process never takes up more than 1% of my CPU.
    Does anyone know what this process is and does? If I quit the process, will it stay off? Any information is helpful. I can't find anything about this specific problem anywhere.

    I would begin looking at any of your 3rd party software, startupitems, background processes, Safe Boot, as well as cleaning the caches with Applejack.
    Many programs and utilities have a "check for updates" feature.
    And the more utilities you have running, to "monitor the health of _________" - they all affect system performance. Less is more. They can stumble over each other and even outright conflict.
    I would also be concerned with the health of the drive directory and folders and the size of the largest folders (there is still a limit of something like 2048 items per folder which will affect open-save and navigating).
    If you have Disk Warrior 4, use it, if you don't, consider it a good investment (just like good backups) for preventative maintenance, not just after there is a problem.

  • Why is there now unusually high, constant disk activity on my Mac?

    Firefox 9.0.1 on Mac OS X 10.6.8 is churning my HD and then must be force quit. It seems to run but there's definately something new and unusual happening here.

    Thanks for taking the time to reply.
    You are right in that there are a lot of guides around to creating "fake" RAC clusters, however Hunter's guide appears to be one of the best and I found it while browsing around the Oracle website. Of course Oracle stress that it is entirely unsupported and for "education purposes" :)
    Well education is what I'm after and I accept that it would perform nowhere near a real cluster. Still the performance issues I'm having appear abnormal.
    The background to this is that one the applications I manage at work (Vmware) has a backend DB hosted on RAC. There is an entire database team who look after this area. For my own personal edification I'd like to learn a bit more about RAC (and Oracle in general) and get my hands dirty, though I currently have no long term aspirations to become a full fledged DBA. I'm working through a text on Safari and I thought it would be useful to create a "fake" as you put it cluster at home and play around a bit. Unfortunately the resources to create a "proper" environment are currently not within my means:(
    With regards to my problem I was hoping someone here has played around with a similar setup and could advise whether they had similar issues. The 3 days or so I spent labouring through the 60 page guide was far more educational than just reading a text.
    I've found that the excessive disk activity appears to be down to my server and Vmware ESXi rather than Oracle. I stopped all instances and CRS and the constant disk activity still continued. I had taken number of snapshots of each linux node during my installation and I'm currently deleting these to see whether this improves things. My hard disk could well be the bottleneck as ESXi is really meant for SCSI controllers and disks if using local datastores.
    I'll take your advice and have a trawl through Ebay. I will also install standalone oracle on a seperate box and have a play with that.

  • Constant disk activity on 2 node RAC 11g cluster - Can anyone help?

    Hi Folks,
    My first post on the forum so I hope you go easy with me.
    I'm new to Oracle, and thought that the best way to get into it would be to dive in and build an experimental RAC cluster on my home network. To this end I used Jeff Hunter's "Build Your Own Oracle RAC Cluster on Oracle Enterprise Linux and iSCSI" guide.
    My only departures from the guide is that I've modelled the architecture entirely within Vmware ESXi on a single quad core Opteron server (HP ML115 G5) with 8Gb RAM and a 1 Tb SATA hard disk. I've also used Openfiler 2.3 for the iSCSI storage rather than the deprecated 2.2. I therefore have 2 Virtual Machines running Oracle Enterprise Linux 5.1, and a 3rd VM running Openfiler 2.3. Each VM has a second virtual NIC connected to an isolated vswitch which functions as the RAC interconnect network.
    I've completed the configuration of the cluster and all the checks (as per the article) report that everything is a-OK.
    However I've noticed that there is a high rate of disk activity on my server, which continues constantly. I've left the server running overnight and the continuous disk activity is still there! :(
    I also noticed yesterday that I could not stop the first instance using either the instance specifc srvctl stop instance -d orcl -i orcl1
    or the global srvctl stop database -d orcl. In both cases the command appeared to hang. I had no problems stopping the second instance on the other node though. Not sure whether this is related.
    So - does anyone else run a similar "single box" setup, and if you do are you noticing similar constant disk activity? If not could you recommend any troublehooting steps I can take to determine the root cause? While the disk activity is contant, the "bursts" appear random, so it looks like something is going on. Not sure what though! :)
    Any replies would be much appreciated.
    Peter

  • FF 18.0.1 constant disk activity after 1 minute with no tabs open

    FF 18.0.1 on Windows XP SP3.
    Within 1 minute of starting FF I observe constant and excessive disk activity.
    I am unable to use any other applications due to the response time.
    I have closed all tabs and disabled all plugins.
    I have just started a FF "reset to factory default", but pop-up window for "Please wait while Firefox cleans up your old data" has been running for 15 minutes.
    Any ideas?

    It sounds like you've got some other problems on your computer as well.
    Restart your PC, then try the steps at http://www.microsoft.com/atwork/maintenance/speed.aspx#fbid=6pXkdz7T_94 to try to clean your computer up.
    After that, Try to reset Firefox again.

  • The Background File Activity Window Is Annoying. Any tips on removing?

    So, I just started using Dreamweaver CC after having been on hiatus from the program for nearly a decade. I have to say, most of the things I hated it for, and stopped using it because of, have been corrected. Kudos, Adobe, for fixing what was everyone's least favorite program in the suite.
    Anywho, all that said, I am still annoyed on a very VERY regular basis by the program issuing an extremely pesky pop-up window anytime I attempt to Put files to my Remote or Testing server. I took a screenshot of the nasty bugger and have attached it here. The Background File Activity window closes when the Put action results in no errors or warnings. That's fine, but EVERY SINGLE TIME I put an HTML file that has references to external files (**so ya know like ANY HTML FILE EVER**), the window stays up and requires me to take action on closing it. THIS IS EXTREMELY ANNOYING. The error message displayed in the window doesn't even seem to be accurate (- error occurred - Access denied.  The file may not exist locally,  may be open in another program, or there could be a local permission problem), because it DOES put the HTML file in question. Perhaps the worst characteristic of this window is that is floats above everything else on my desktop. That means if I want to do a local>remote sync or just upload a bigger bunch of files, and then jump back into Photoshop to keep working on assets in there, I eventually am interrupted by this window popping up. This thing is worse than my cat trying to lay on my hands when I'm typing.
    So, if anyone has any suggestions on how to turn this frustrating dialogue off, I would be very grateful.
    My system specs are: Yosemite (Mac OS 10.10.1) and Dreamweaver CC 2014.1 (15.0.0.6947).

  • IMac 27" i7 won't turn on. No disk activity.

    Ive seen some similar dicussions here but none that are exactly like what happened to me.
    The big problem is my iMac is stone cold dead. I push the power button and nothing happens, no disk activity, no fans, no nothing. As if it had been un plugged.
    I dont know if it could be related but I was sing Boot Camp. I created the partition, it asked for the windows disk, I put it in. the iMac restarted, I got the chime and the gray screen (no apple logo). I was expecting the windows installer to start up, no luck. The iMac was on the gray screen for several minutes, then the apple logo appeared and then I got the log in window. I thought it was strange so I restarted and held down the "option" key, I got the gray screen for several minutes again. I then got the boot menu where I could see "Macintosh HD", "Bootcamp" and "Windows"(DVD). So I booted with the windows disk thinking it would start up the installer. Several minutes went by and it was still on the same screen. Then it restarted by itself, I heard the chime. Mind you, I had unplugged all the external hard drives I had and what not. So I pressed down on the touch pad to eject the windows disk. The disk ejected and the iMac got stuck on the gray screen for several minutes again. It restarted by itself. I thought I would leave it to boot all the way into Lion again. This time the gray screen didnt go away, I waited for over 20 minutes, got frustrated and pressed down on the power button for a hard reset. I powered on again, got the chime, then I got a black screen with white text saying it could not find a boot device. So I thought I would restart and hold down option key to boot from "Macintosh HD". I powered it down, and it never powered on again. That was it. No Hard drives spinning, no fans runnig, nothing.
    I checked the outlet, plugged the iMac to a different outlet, checked the power cable, etc. It all seemed fine.
    I reset the SMC, several times in fact, and nothing.
    I even opened the Memory Access Door and removed and put back the memory cards. Not sure why, but Im desperate.
    So Thats it. Im gonna take it to the apple techs but I thought I would get some comments from the community. Any ideas??? . Any help is appreciated.
    iMac specs:
    3.4GHz Quad-Core Intel Core i7
    16GB 1333MHz DDR3 SDRAM - 4x4GB
    2TB Serial ATA Drive
    AMD Radeon HD 6970M 2GB GDDR5

    Sounds like a failed power supply. Because the machine is covered by warranty take it into your local Apple Store or AASP for service. Make sure you book an appointment first. You can try doing a SMC reset and Pram reset first but I don't think they'll work.
    SMC RESET
    Shut down the computer.
    Unplug the computer's power cord and all peripherals.
    Press and hold the power button for 5 seconds.
    Release the power button.
    Attach the computers power cable.
    Press the power button to turn on the computer.
    PRAM RESET
    Shut down the computer.
    Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the second time.
    Release the keys.

  • "Disk Activity" monitor for multiple hard drives?

    Is there something like "Disk Activity" in the Activity Monitor utility to show which hard drive is accessed? I put a SSD in my Mac Pro but it occasionally hesitates for a few seconds as if it's accessing a file on one of the other three (slower) hard drives. I want to see a list of files that it needs that aren't on the SSD, so I can move them over and speed up my computer, or remove the extra hard drive eventually.

    Yes, it's possible.
    However for the maximum length I have not figured out.
    I haven't found a reason to go past 16 characters.

  • JPDA debug slow, CPU low, no disk activity

    I tried to debug using JPDA with a Tomcat 4.0.3 target container. If I am very patient it finally connects after some good minutes. After that it debugs, even if rather slow.
    However, during those minutes nothing seems to happen. CPU is low (under 5%), and there is no disk activity.
    JDK is 1.3.1_02, W95 (yes, still), 256M.
    Any ideas?
    Thank you,

    JDK is 1.3.1_02, W95 (yes, still), 256M.JPDA is really slow in Hotspot/Classic before JDK 1.4 (it's interpreting all the bytecode vs. running it natively). Try using classic if it's available instead of hotspot, it seems to be a bit faster at debugging.
    Also, if you can, try JDK 1.4. It's JVM is MUCH faster at debugging than 1.3 is.

  • Computer unresponsive with disk activity, even when disk is USB

    Hi,
    I've always had issues with responsiveness with Linux when there is disk activity (several distro's, same hardware), whereas a Windows XP installation reacts very snappily. When I have a torrent client open, Mplayer keeps hanging a few times a minute (even more often when the download is going fast (2 MB/s)).
    Recently I migrated to ext4 in the hopes that would fix it, but it didn't. It's also not something as simple as a DMA issue (because it's SATA). Disk throughput is about 80 MB/s, which is OK.
    Anyway, currently, I'm performing this on a USB disk:
    dd if=/dev/zero of=/dev/sdc1 bs=10M
    And even then the computer is almost unusable, which it shouldn't be, because the internal disks are not used for this. And some time back when I was copying an AVI to a USB stick, it was utterly unusable.
    Maybe it's a driver issue, because I can't imagine the normal schedulers being so horrible, but I can't say.
    My disk controller can't be accessed with AHCI (there is no 'native' option in the BIOS), yet NCQ is enabled:
    # dmesg|grep -i ncq
    [ 1.313605] ata3.00: 2930275055 sectors, multi 16: LBA48 NCQ (depth 0/32)

    [ 2.324738] ata6.00: 488395055 sectors, multi 16: LBA48 NCQ (depth 0/32)
    I have kernel 3.1.1-1-ARCH, so I should have the 'wonder patch'.
    Hardware:
    CPU: Athlon X2 3800+ (2GHz dual core).
    RAM: 2 GB DDR400 RAM.
    Chipset: Nvidia nForce 4 ultra.
    Disks (in MD RAID1): 2 WDC WD15EARS-00Z5B1 (disks have changed over the years) and 1 Seagate disk (which contains windows and is spun down in Linux, to prevent noise).
    I disabled the (self-destructing) head parking feature of the caviar green disks with WDidle by setting the timeout to max (disabling the head parking with WDidle actually lets it trigger constantly, that's why I chose this way).

    Anybody know what might be causing this?

    I recently tried to play around with the schedulers and I found out that using "deadline" for my internal drives, "cfq"  for my optical drive and "noop" for everything else. I tried copying a load of small files on my USB flashdrive while playing a movie from the optical drive and the system felt very responsive.
    I've been playing some more, and you're right in that it seems that with the internal disks at deadline, the system is a lot more responsive. Previously, I put the external disk I was zeroing at deadline too, but that (I know now) made it worse again.
    I run a 3.2-rc5 kernel which seems to help considerably though.
    Has there been any specific change in that kernel to cause that?
    BTW, I noticed that the NCQ queue on your drives is of 0 length, try setting it o 31 like this (as root).
    I always wondered about the NCQ queue. In pages about NCQ that I found, the dmesg also reported a queue of 0. I just always figured it meant how many commands it currently had, being zero at boot time.
    When I do "cat /sys/block/sda/device/queue_depth" it always says one, regardless of disk activity.

  • [SOLVED] High disk activity after kernel boot

    Hi,
    after kernel loading (just before getty starts) i notice extremely high disk activity for ~20 seconds for no reason. I think that it is something related to systemd and mount services.
    When i set rootfs to read-only in syslinux kernel parameters then the system starts normally without delay. So, i think that something is constantly writing to (or checking?) my hard disk right after boot sequence.

  • What can I do about my 20 inch iMac (Core Duo) doing a LOT of disk activity?

    What can I do about my 20 inch iMac (Core Duo) doing a LOT of disk activity?
    I have iStat and can see the disk activity which halks other operations till it finishes.
    Is there some built-in Optimization software I should use?

  • No background processing active on TargetServr BWTCLNT400

    Hi There
    I am currently working on a landscape where we have had a copy-back on our CRM system, plus the BW system was moved onto new hardware etc etc. the net result is that I am having a nightmare re-establishing the comminications CRM --> BW (which is now sorted) but especially BW --> BW.
    I have sorted out all the usual stuff (SM59, WE20, WE21 etc etc) but when I run an update from an DSO in BW to another InfoProvider using the 3.x data flows, I get the following error in SM21:
    BP_JOB_MODIFY: Job cannot be modified. Reason:
    > Job BIREQU_62ZSSTFTQ5AI5RW1Y429235SE contains invalid data
    BP_JOB_MODIFY: Job cannot be modified. Reason:
    > No background processing active on TargetServr BWTCLNT400
    I suspect this has definitely something to do with me trying to sort out the process chains and de-scheduling the background job for BI_PROCESS_LOADING on the BW system.
    When I try to re-shedule this job using SM37, where you define a step for the ABAP Program RSPROCESS the system insist that I should enter a variant (which does not exist). So obviously I am being a muppet.
    Does anybody know how I can re-start the Background Processing (I suspect there is a program that needs to be run or something)?
    Any help would be MUCH appreciated.
    Cheers - Daneel

    Thanks for your reply.  I don't use itunes so that couldn't be it.  Reading about Little Snitch and Hands Off, however,  educated me about the data harvesting in many apps and that when buying from the AppStore one will more likely get Apps with benign data harvesting.
