[Condor-devel] Java universe and memory

[Craig Bruce <pcxcb1@xxxxxxxxxxxxxxxx>]

Hi, 

I'm successfully using 7.0.1 on a linux pool. We run a lot of java jobs that
use lots of RAM. It is not unusual to underestimate the amount of RAM we
need to pass to the JVM:
java_vm_args   = -Xmx900m

If it isn't enough the JVM will not complete the task and the error file
confirms this:
java.lang.OutOfMemoryError: Java heap space

However, condor will evict this job and thus resubmit somewhere else. As the
memory value has not been altered the same error will result. Should the
task not just complete in this case? Otherwise users think the job is
running/waiting to rematch, but really it needs cancelling, modifying and
resubmitting.

Thanks
Craig
