Issue/Introduction

EPA running on VMWare impacting application memory.

 

 

Cause

Customer misunderstanding of looking at virtual rather than resident memory in top.

Environment

Release : 10.7.0

Component : APM Agents

Resolution

EPA Agent is not the culprit.APM only controls the heap  within the JVM (resident memory). It has no way to close resident memory. And resident memory is tied to JVM heap. The resident memory for the agent was well within specifications.
