When everything hangs, can you kill the java compile process immediately
and have everything unfreeze fairly instantly? Or does it take a while
for things to settle down? Is your hard drive light going light mad
when things are hung? What is your load average during the hang? Are
any processes in the "D" or uninterruptible sleep stage? If you run top
and sort by memory usage, how much VSS/Virt are your largest processes
(shift-m to sort by that)? What is your swap file usage at that point?
I agree with Todd, that this problem could come from Java causing thrashing.
Or it could be that your hard drive has I/O errors in the place where
Java is working.
