Hello,
I have some trouble with a multithreaded java network server running on
SLES10. At random times I see the kernel take 80% of the CPU leaving iddle
to 0% for 30 seconds. After this period the system returns to normal
operation state.

I am using nabble's interface to post messages ( www.nabble.com ) and I am
not subscribed to the mailing list, so it's possible that this is the cause
