Hi Vivek, Are you able to obtain some stack traces from the application when it's using 100% CPU? If it is indeed the RawStoreDaemon that's consuming the CPU, the stack traces might give some clues. Post only the traces for the daemon thread of you like. Also, what's the version of your Derby installation? Regards, -- Kristian > > Thanks. > Vivek > >
