"Your Mac OS X startup disk has no more space available for application memory" error?
I've searched the web high and low to resolve this issue, tried many different approaches, and have not been able to resolve it. I'm really looking for help at this point.
I'm trying to export a 5 minute video that I've put together using FCPX 10.0.8. I export "master file" to an external hard drive and at some point in the export process I get the following popup:
System information:
- 13" mid-2011 Macbook Air
- Processor 1.8 GHz Intel Core i7
- Memory 4 GB 1333 MHz DDR3 (2GB x2)
- Graphics Intel HD Graphics 3000 384 MB
- Software Mac OS X Lion 10.7.5
- Hard drive: 256 SSD (107 GB available)
FCPX project information:
- FCPX media is stored on SSD system drive and exporting to external drive
- Media is 1080p 24 frame footage shot using a Canon T2i
- Total Length of project is 5:13
- Background rendering is off
- Proxy media is created for all media but I am exporting original media
I've tried the following:
- Freeing up more hard drive space - I've anywhere from 25 GB to 107 GB free and it does not seem to matter how much free space I have, I still get the error
- Repairing system drive - I've repaired permissions with Disk Utility and I've even performed a drive Rebuild using DiskWarrior
- Cleaning up FCPX project - I've gone through and deleted all unused media, deleted project and event render files, etc
- Cleared RAM - During export I've repeatedly ran MemoryKeeper to clear RAM and free up more memory
- System restart before attempting the export and I also boot up holding 'shift' which blocks unnecessary background tasks, dropbox, etc from starting
Considerations/Observations:
- I've exported longer and more complex projects using the same setup with no problem, also with less free disk space
- I've never seen this error in any other situation
- The error will pop up anywhere from the export being 35% to 98% completed
- Activity Monitor during export:
- The only processes that are taking up any considerable memory are FCPX and kernal_task
- '% CPU' on FCPX jumps around from 60% or less to 250% or more
- FCPX usually has 83 threads
- 'Real Memory' for FCPX can be anywhere from 300 MB to 2 GB
- It seems that when the export is at about 25% or 30% that is when the computer starts slowing down, 'Free' system memory goes down to mere megabytes, and a ton of swapfiles start to generate in .../var/vm folder which will build up until I'm out of disk space
- Sometimes the error will pop up even before I run out of disk space due to the swapfiles. Last time it came up when I still had 40 GB free

Thanks in advance to anyone willing to help me figure this one out!
