CallManager Service Restarts

[j.shrewsbury]

Greetings,

We have a CallManager running 4.1.3(sr3a). About 1-2 times a week the CallManager Service restarts. At first I thought this was occurring at the same time as backups, but I have since discovered that is not the case.

We have noticed this for more than one customer running different versions of CallManager. It is usually occurs after hours, and most of the time it is not occuring at the same time as backups.

The last time this occurred there were a lot of transient connections events in the app log, and then the last entry before restaring in the event log is SDL error for connectivity to the sub. (also this appears to happen on the pubs).

Any ideas?

you could enable some detailed traces to help you find this.

try the following for starters and then be sure you can capture the event:

trace>configuration>ccmIPaddy>ciscoCallManager

set the debug trace level to detailed.

set the traceOn checkbox to checked.

set the enableFileTraceLog checkbox to checked.

check the following checkboxes:

enableCMrealTimeInformationServerTrace.

enableMiscellaneousTrace.

enableCDRtrace.

enableMediaResourceManagerTrace.

enableKeepAliveTrace.

these are good for starters and will keep the logs to a minimal for now but you can check the other options to trace as well if you need to.

now, click the 'SDLconfiguration' link to the upper right so you can turn on SDLtrace. enable the following for starters:

check the following SDL checkboxes:

allLayer1Trace

allLayer2Trace

allLayer3Trace

gatewaySignalsTrace

allCallControlTrace

miscellaneousTrace(databaseSignals)

UUIEoutputTrace

CTItrace

defaultTrace

SDLlinkStatesTrace

signalDataDumpTrace

SDLprocessStatesTrace

SDLtcpEventsTrace

lowLevelSDLtrace

SDLlinkMessagesTrace

the SDLs are tougher to read so if you need help, post some results and we can assist :)
