[cisco-voip] Dropped calls on CUCM 6.1 cluster

[Wes Sisk]

or upgrading to get fixes for all of the known memory leaks :-)

you could also harass your account team for a fix to:
CSCsi21579    allow scheduling commands

The ability to schedule a restart would automate the process after hours to ensure uptime during business hours.

Wes

Dennis,
We think so yes. The users were not logging incidents anyway (although typically they cant tell me exactly when they stopped having issues and some are saying they are still having issues although I suspect it might not be the same thing) The restart of the service only dropped the virtual memory usage to 65% from 85% however and now it has crept up again to around 70%.
Am I stuck restarting the tomcat service every other week then? 
Cheers,
DT

Tomcat has memory leak throughout the ccm rev’s. Does restarting the tomcat service impact the frequency of dropped calls?

Cheers Wes and Kiran,
On a possibly related note our Publisher server has started popping up Virtual Memory errors as copied below
 
Available virtual memory below 30 Percent.
tomcat (884 MB) uses most of the memory.
 
Could this be related? Is it something major that needs to be sorted?
Cheers,
DT

Hi,
We are getting calls disconnected mid-call on random handsets in our CUCM 6.1 cluster( 1 pub 2 subs), actually it seems to be phones on one particular subscriber that are experiencing the issue but that might be a red herring. The users say it is happening on all types of calls but we are trying to get more detailed info from them atm.
Does anyone have any ideas how can I start to track this down? Please be as basic as possible so I can understand :-)
Many thanks,
DT
