We have a Cluster with a Pub and 4 Subs. Every 60-70 days, we start getting a low virtual memeory alert on the Publisher.
The threshold is set to 30% on RTMT (which means that when Virtual memory becomes less than 30%, RTMT will start alerting). We have to reboot the Publisher to get rid of this alert.
CUCM version is 6.1.3.3190-1 .
The Publisher server stats are -
HW Platform : 7835H
Processors : 1
Type : Intel(R) Xeon(TM) CPU 3.40GHz
CPU Speed : 3400
Memory : 2048 MBytes
Is there any Bug associated with this CUCM version that could be causing some kind of a memory leak?
There are 2300 phones in the cluster and none is registered to the Publisher.

Hi
Not sure of the specific bug, but I had one customer on 6.1(3) with very similar issues and upgraded them to 6.1(4) SU2 a few months back and all has been well for them since...

I tried the solution described in the following document but did not work. After restart the CiscoTomcate Service alert remains.
