Hi,

Could you paste the logs for the server process. Also, check the maximum permissible size on your WebAs server. From your inputs you said that this problem occures after some time gap working on EP does that mean till the time Server was up and running. If it is the case then check your applications which is consuming maximum memory and check the in the logs for GC. If GC is more then this must be application problme. Post the logs and will check after that.
