[jboss-user] [Performance Tuning] - Re: 100% CPU usage with lots of memory

[Juvenxu]

Hello PeterJ,
I have exactly the same issue as you.what I have seen is that  there are a lot of I/O operations under the following path:
"$JBOSS_HOME/server/default/data/tx-object-store/HashedActionStore/defaultStore/StateManager/BasicAction/TwoPhaseCoordinator/AtomicAction".
These I/O operations consumed a lot of CPU,because Jboss kept generating files under this path. Does anybody have idea of this?
Thanks a lot
