Unity connection core dump - CuMbxSync

Kapil Atrish

Level 3

Hello,

Unity connection: 8.6.2.23900-10

Unified Messaging with Office 365 / auto-discovery

I am getting following core dumps and voice-mail to e-mail stopped.

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

At Wed Aug 28 17:45:46 EDT 2013 on node 10.10.30.254, the following CoreDumpFileFound events generated:

TotalCoresFound : 1

CoreDetails : The following lists up to 6 cores dumped by corresponding applications.

Core1 : Connection Mailbox Sync (core.1269.6.CuMbxSync.1377726312)

AppID : Cisco Log Partition Monitoring Tool

ClusterID :

NodeID : cmbe8

I did a bug search and found some relevant ones but the conditions didn't match exactly except for the following:

CSCtz31625 - CuMbxSync Cores while logging Autodiscovery diagnostics

Workaround:
Disable CsExMbxLocator INFO level Micro traces (Trace Number: 12)

I have already confirmed that the above trace is not enabled but I am still getting core dumps.

Upon analysing the Core dump file, I see the following error but I am unable to find anything relevant on this error:

+++++++++++++++++++++++++++++++++++++++++++++++++++

Core was generated by `/opt/cisco/connection/bin/CuMbxSync'.
Program terminated with signal 11, Segmentation fault.

+++++++++++++++++++++++++++++++++++++++++++++++++++

I have double checked, we are not using special characters in User names which may have been another possible cause for the core dump.

I'll appreciate any help on this. I am attaching the Core dump file if someone would like to have a look.

thanks,

Kapil
