EM Incident: Warning:New: - Agent resident memory utilization in KB is 251,848

If an EM Agent consuming more memory on the server, please do the below work around to resolve the issue.


1. ./emctl stop agent

Ensure no EMAgent process is running with the following commands:

<AGENT_HOME>/bin>./emctl status agent

$ps -ef | grep TMMain
$ps -ef | grep emagent
If you see any process, please kill them.

2. Take a Backup and edit the .../agent_inst/sysman/config/emd.properties file:

from:
agentJavaDefines=-Xmx128M -XX:MaxPermSize=96M

to:
agentJavaDefines=-Xmx512M -XX:MaxPermSize=96M

and save the file.

3. Start the Agent and check the status:

<AGENT_HOME>/bin>./emctl start agent
<AGENT_HOME>/bin>./emctl status agent 


It should Fix the issue. 

If still does not resolve the issue please change the below Open Files parameter value.
