Error: "Unable to allocate memory..."

This used to happen only on quit, as described here: http://forums.adobe.com/message/5806716#5806716
It also would happen if I started up AE by double clicking a project file, as opposed to launching the application, then opening a project file once the application is open. In this case, the error message would continuously pop up after hitting OK, preventing me from doing anything. I would then have to force quit.
Now, I am completely paralyzed because no matter what I do, I get this error as soon as I open a project and no matter how many times I hit OK, it keeps popping up. I then must force quit every time. AE is completely useless at this point.
I have tried reinstalling (preferences as well) to no avail. Totally stuck here.
After Effects CC 12.1.0.168
Mac OS X 10.9 (13A603)

Update: I emptied the disk cache and it seemed to resolve my specific issue which wasn't allowing me to use AE at all. But I'm still getting the standard error on quit explained in the link above. I'm sure it will be fixed in an update soon.

  • AE CC Error: "unable to allocate memory"

    Continually get this error: "unable to allocate memory. Decrease the memory requirements for the rendering of this frame, or install more ram."
    I have been working on the same AE project-- 30mb project mostly full of animated shape layers. While working in this project this last week I keep getting the same error on both my macbook pro (8gb ram) and my imac desktop (16 gb ram) which makes me believe the issue is not my computer(s). 
    I initially got the error using AE CC version 13.0.2. After reading different forums someone suggested downloading the updated 13.1 version which fixed some bugs. I did that on my macbook pro and within minutes of working still got the same error.
    Then I down-saved the AE project to CS6, started working on it again in CS6 and quickly received the same error.
    I've also cleaned out my cache folders, but still nothing.
    I have spent hours investigating this issue and am at a complete loss on what to do. Super frustrating when working on a tight deadline!!
    Can anyone help?!!

    The project contains a lot of stuff:
    -Shape layers with repeaters to create animated sprites and animated backgrounds
    -created wiggly text using precomped textures with fractal noise, displacement maps and posterize time effects applied. Here is the tutorial I recreated: Jittery Type After Effects Tutorial - YouTube
    -imported mini AE projects of different animated objects that I used in past projects: book with pages flipping, dollar bills flipping in stack, coins stacking up, box unfolding.
    -More effects used- fill, drop shadow, bunch of track mattes, turbulent displacement, hue/saturation, exposure, cc bender- on flipping pages in book,
    -Lots of precomps mostly 1920 x 1080 some bigger like 1920 x 3000
    Would it be possible or helpful if I just sent my project and files for you to inspect?

    Hello,
    Based on the error, unable to allocate memory for mutex; resize mutex region,
    have you tried increasing the mutex region?
    The documentation on the setMaxMutexes method is at:
    http://www.oracle.com/technology/documentation/berkeley-db/db/java/com/sleepycat/db/EnvironmentConfig.html#setMaxMutexes(int)
    You can run db_stat -x
    to display the mutex subsystem statistics.
    You'll see the information for statistics like:
    Mutex region size
    The number of region locks that required waiting (0%)
    Mutex alignment
    Mutex test-and-set spins
    If that does not look to be the problem, just let me know.
    Thanks,
    Sandra

  • Urgent help with ORA-01062: unable to allocate memory for define buffer

    Hello, Folks!
    I have a c++ code that is using OCI API that is running both in
    windows and in spark.
    (The same c++ code compiled and running in both platforms)
    and asking the same query.
    In windows, everything is OK but in spark
    it failes...
    The ORACLE Server is installed on win2003 station
    Both client and server ORACLE version is 10.2.0.1.0
    The code is running on spark(oracle instant client is installed)
    This query is a simple select query that selects only one field
    of type VARCHAR2(4000) (the same problem with happen with any
    string type field larger than 150 characters)
    The error occured when calling for OCIDefineByPos method
    when associating an item in a select-list with the type and output
    data buffer.
    The error message is: ORA-01062: unable to allocate memory for define
    buffer
    (This error message signifies that I need to use piecewise operation...)
    But it happens even if I make this varchar2 field to be of size larger
    than 150.
    It is not fair to use piecewise fetch for such a small fields sizes.
    May be there is not configuration setting that can enlarge this
    I know that I wrote here a very superficial description.
    If somebody knows something about this issue, please help
    Thanks

    I had a special luck today after searching the solution per weeks:)I have got a solution.
    When I get the size of the oci field, in the following expressioin
    l_nResult = OCIAttrGet(l_oParam->pOCIHandle(), OCI_DTYPE_PARAM, &(orFieldMD.m_nSize), NULL, OCI_ATTR_DATA_SIZE, m_oOCIErrInfo.pOCIError());
    orFieldMD.m_nSize was of type ub4 but according the manual it must be ub2.
    As a result, the number returned was very large (junk?) and I passed this value to OCIDefineByPos
    Now I changed the type and everything is working!!!
    In windows there is not problem with this expression :)
    Thanks

  • After Effects Error: Unable To Allocate Space...

    I have never seen this before...I am stumped.
    I am on After Effects 8.0.2 on a PC at work (Windows XP Pro 2002 SP2 / Intel Xeon 3.6 Ghz / 3.25 GB RAM) and I keep getting the following error when rendering:
    "After Effects Error: Unable to Allocate Space for 4290 x 4590 image buffer"
    My Comp is nowhere near that size (1280 x 720) nor is anything in it (PS document 1200 x 1500 / 720p video / solids are comp size). I have reset Cache sizes until I am blue in the face / have enabled Disk Cache / dumped preferences / cursed at the machine / nothing works.
    Any suggestions would be appreciated...thanks.
    Joey

    Just thinkin; out loud, so sorry if it's stuff you've already considered, Joey:
    Any scale settings expanding objects beyond the size of the comp? Text especially can blow out memory when scaled up large.
    Same goes for 3D objects close to the camera.
    As you're a Mac-o-file you've probably been saved in the past by the extra RAM accessible - SP will only give AE 2GB.

  • After Effects error: Unable to allocate space for image buffer

    I am having some glitchy issues with After Effects, very inconsistent, but I am getting the error message "After Effects error: unable to Allocate Space for a 7500 x 4500 image buffer. You may be experiencing fragmentation. In the Memory and Multiprocessing Preference dialog box, trying increasing the RAM to leave for other applications, and selecting the Enable Disk Cache option in the Media & Disk Cache Panel".
    Pretty straightforward, but I have a brand new 8 core dual 2.25 Mac Pro with 16GB Ram. I have it set to allow other applications to use 7GB, have jockeyed that setting between 1GB and 5GB and still gotten the same error message. Disk Cache is set to 3GB, have pushed it all the up to 7GB and still gotten the same message. I am working in 1080p, but I got the error message with Open GL on, quarter resolution, and wasn't even trying to RAM preview. I also noticed that with a straight 1080p clip .mov animation codec clip, after effects will only RAM preview about 7 seconds. That is without any other layers or effects.  I do not have all of my source footage in one folder, I am going to try that next. I am running of a fast internal hard drive that is not they system drive.  It also seems like it happens after I have been using the comptuer for awhile. If I restart the problem will usually go away for a little while.
    I think that I may have a bigger system error, the computer locked up bad once after I had it for a few weeks and since that happened CS4 has been unstable in general, especially Photoshop and Bridge. My guess is bad RAM, but I wanted to make sure I wasn't missing something with my AE settings.  If any one has any input please let me know. Thanks.

    > I lowered the minimum RAM per core to 1GB, because the Adobe site recommends that as a base setting for andHD project
    When you say "the Adobe site recommends", what exactly are you referring to? If you're quoting recommendations written for After Effects on the Adobe website, you're very likely quoting me. And this is what I wrote in the Help document:
    "Memory & Multiprocessing preferences":
    "The amount of RAM required for each background process varies depending on your system configuration; at least 1 GB per process is recommended. Optimum performance is achieved with computer systems with at least 2 GB of installed RAM per processor core."
    This blog post gives essentially the same advice, but with more explicit suggestions.
    But, as I say at the bottom of that blog post, if you find that some other settings are working better for you, that's great. Every project and computer system are different. Do what works for you.
    > Also, if it is an
    dual quad core system, there should be 8 cores, but in the
    multi-processer preferences panel it lists CPU's as 16.
    The number of "virtual" processors can be double in a system that uses hyperthreading. After Effects doesn't actually treat these as separate processors in this context, though.

    ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL
    I did a "ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL" to stop the log shipping on DR server but the command is hanging.
    I also tried freeing up the disk space in my flashback drive but I think it won't help as indicated in the error message:
    "DO NOT manually remove flashback log files to create space".
    What is the best way to set the DR server back to normal operation?
    I do not need the flashback logs and will disable the flashback once this is rectified.

    You might look for command line options that allow you to change the heap size. Try making it smaller.
    You might also want to verify that the 'java' you are running is actually the binary that you think it is, versus a script/link to someplace weird.

    I am trying to use my ipod touch for the internet. When I try to go to a site I get the following error.

    The error was: "Operation could not be com0pleted.

    How do I get past this error

    If you haven't already done so, I'd suggest rebooting your iPod. This isn't the same as turning it off with a quick tap to the button on top. Quite often a reboot of a computer will clear up a temporary memory issue. From the ipod touch manual:
    Press and hold the
    Sleep/Wake button on top of iPod touch for a few seconds until a red slider appears,
    then drag the slider. Then press and hold the Sleep/Wake button until the Apple logo
    appears.
    Hope this solves it and you don't see the error again.

    }

    Hello,
    I am still looking into this, but upon closer examination here is the situation, basically as reported.
    The test calls set_thread_count which sizes the memory. In __env_attach(), (dbenv->thr_max is used to size the region. So you are correct, the higher the value used in set_thread_count, the larger the size of the region will be. Eventually that memory will be depleted, and __env_alloc_size() returns ENOMEM, after multiple calls to system(db_stat). __env_alloc_free() is not called. This is the part I am still investigating.
    The test uses system to fork a separate processes for db_stat and the failing stack is:
    lt-db_stat: assert failure: ../dist/../env/env_failchk.c/426: "ret == 0"
    lt-db_stat: __os_stack+0x2b
    lt-db_stat: __os_abort+0x1d
    lt-db_stat: __db_assert+0x47
    lt-db_stat: __env_set_state+0x53c
    lt-db_stat: __env_attach_regions+0x38b
    lt-db_stat: __env_open+0x154
    lt-db_stat: __env_open_pp+0x334
    lt-db_stat: lt-db_stat
    So db_stat is opening an environment, attaching to its region, and then __env_set_state() calls __env_alloc(). It is __env_alloc() which fails with ENOMEM after some point when there is no more space to be allocated from the shared region. And I'm still looking into that space would be returned to the shared region.
    Thanks,
    Sandra

  • PDA error: Unable to lock memory chunk

    When I try an run a PDA build on my pocket PC I get the following error:
    "App failed. Error code 130437003. Unable to lock memory chunk."
    anyone have an idea of what this error refers to?

    Hello Jim77215,
    This kind of error has previously been reported when using a CF6004 and DAQmx Base.  If you are not using any of these products you may want to post more information about the PDA Operating System, Large Fonts Enabled, Localization (Non-English), Version of LV PDA, and model.
    If you are using DAQmx Base with the CF6004 try this work around.
    1) Force a recompile of your VI by holding the shift key and clicking the run arrow, and then try running it on the PDA.
    If this does not work and you are not using LV PDA 8.0.1 and DAQmx Base 2.0
    1) Close LabVIEW
    2) Go into the C:\Program Files\National Instruments\LabVIEW x.x\vi.lib directory and rename "_DAQmxBase" to "DAQmxBase" (remove the underscore at the beginning).
    3) Open a blank VI and copy all the DAQmx Base API VIs in your VI (Start, Stop, read, write, and is task done) to the block diagram. Either drag and drop them or use "Select a VI..." from the palette.
    4) Switch execution target to the PDA.
    5) Save the VIs and close LabVIEW
    6) Rename the "DAQmxBase" directory back to "_DAQmxBase"
    7) Run your program
