Hum...I've no idea since Grizzly is bypassed when mod_jk is used. Next
time the high CPU happens, can you try to get a thread dump (using
jstack or kill -3)? Better, can you do (not sure prstat exist on Linux)
% prstat -Lp <java PID>
% pstack PID/LWPID
Then match the result:
> f8800278 ???????? (c497fcb8, c497fe80, a, ec2ff250, f880d120, c497fdb0)
The last line ??????? contains the thread ID: c497fcb8.
Then kill -3 PID and match the thread id. We will know which thread is
eating the memory.
Hope that help.
Thanks
