CUCM 6.1.2 High Virtual Memory Tomcat

Hi, i have a client wich is having problems with the Virtual Memory in the Publisher Server, it start al 30% and grow at 70% in just 2 weeks, after this the services like MoH and some transfers start to FAIL,the RTMT start showing up a Alarm about Tomcat is using too much RAM, the workaround is to start the publisher but this is not an acceptable response to my client.

The CUCM version is 6.1(2)-1000-13

They have 2 more Subscribers but the Virtual Memory is at good levels

Re: CUCM 6.1.2 High Virtual Memory Tomcat

RTMT will show this memory usage based on physical memory and not virtual memory.

Verify that the system is not showing any memory leak.

-Check that the committed memory usage does not greatly exceed the amount of physical memory in the system.

-In most cases, the Total Commit Charge as shown by Task Manager will be only slightly higher than the Physical Memory Total shown.
