Description:

Mounting Old Agents fails with "EM has too many disconnected agents manually mounted, please un-mount the unwanted agents".

Solution:

Try increasing the value of "threshold value" in the "apm-events-thresholds-config.xml" on the EM and recycle EM.


<clamp 	
 	id="introscope.enterprisemanager.disconnected.historical.agent.limit"> 	
<description> 	
 	Limits the # of dead/disconnected agents that are mounted 	
 	state to minimize 	
 	the runtime memory of EM. 	
 	</description> 	
<threshold value="400"/> 	
</clamp>
