Have you deployed some other components on this AS Java?

What are the usage types being run on this server-box? By any chance do you have some of these: DI_CMS, DI_CBS, DI_DTR or DI_NTY?

In case of Out of Memory, you will need to analyse the OOM.hprof file.

The .hprof files are located on:

/usr/sap/<SID>/<AS-JAVA-instance>/j2ee/cluster/server0/

This file is too big to be uploaded on the SAP Community. Besides it is allowed to upload only pictures & screenshots.

Please refer to these collection of blogs:

Analyzing Java Collections Usage with Memory Analyzer

and/or

The official documentation of the Memory Analyzer

If you do face difficulties you might upload the leak suspects report here so I might have a look.
