Low Virtual Memory Alert starts every 60-70 days

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...


Regards


Aaron

Hi,


I have the same problem, a problem that appeared after the upgrade CUCM 7.1 to CUCM 8.0 (3). I attached the error that appears in RTM.

Thanks,
