| Re: Very unstable appserver since Linux move
Kristof,
In addition to the assistance that Nick is giving, I'd recommend bumping up to 2200MB for your WebLogic heap -- as a large part of the issue appears to be Full GC related. I've had a lot of luck on Linux with heaps from 2000MB to 2200MB, though larger helps sometimes run out of native memory. Nick, however, has been successful on some very large sites with heaps as large as 2400MB. I guess it depends on whether your Red Hat Linux OS is 32 or 64-bit and what else may be running on the system.
Scaling back on your OTM threads may also help this, as the system will grind to a halt when all available heap memory is exhausted.
Thanks!
