CUCM not responding

Dear All,

 

In my call manager cluster(PUB and SUB), Publisher is freezing and need a restart the bring the service back. We faced the issue many times, But today after the reboot the node license was missing. After restarting the publisher and uploading the node license the service came back. Please help me in finding the root cause of the issue.

 

CUCM Version: 7.1.5.32900-2

Hardware - MCS-7825-I4-IPC1

 

Thanks

Hi Nibin,First you need to

Hi Nibin,

First you need to check if there was any unclean shutdown of the server using the steps mentioned in the following link

http://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/116717-trouble-cucm-shutdown-00.html

If yes, use the recovery iso or better option would be to rebuild the server as per the doc.

If there is no unclean shutdown then look for the outputs of the following:

utils core list  OR utils core active list

utils diagnose test

If the system freezes again then you need the syslogs, RidDC perfmon logs, proglogs and detailed ccm traces for that timestamp for RCA.

In addition to what Manish

In addition to what Manish has said below, I suggest you also run the file system check using the recovery disc. Also, make sure that the firmware on the server is the latest, which contains the latest bug fixes.
