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

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.
