Past few days the server is runing, but we get this error on the page and we had to restart the JAVA instance from the JCmon, but still it repeats.

Hi,

Your server node is getting restarted. Check the Default Trace at the same timimg. You would be able to find a reason.

Award points if helpful.

Thanks,
