BUG: soft lockup - CPU#0 stuck for 10s! [java:13959]
and alot of other information. ii've took a screen shot of the info shown , you can find it under the following url: http://img585.imageshack.us/i/img00012201103070833.jpg/ and had to hard reset for it to be back up and running.
i tried googling with no luck for direct relevant info. so hoping you can help out
Some real kernel developers might have better insight on why this happens. But this hits APIC timers during a syscall. I would probably try to boot the box with 'noapic' in the kernel command line, to see if this improves things or not.
Do you see the "soft lockup - CPU#0" always? or does it also happen to other CPUs as well? And if it does, is the java process running on more CPUs?
kind regards,
