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. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
