CallManager Version 3.0(6)   No comments.  

Problem Description

Under certain conditions, the CallManager may restart. The problem is a race condition that can be encountered in normal operation with H323/Intercluster trunks. The problem will be noticed when dialing a number associated with a route list to an H323 gateway or another CallManager cluster via an intercluster trunk. If the calling party performs an onhook/offhook sequence during the setup phase of the call, the CallManager's Signal Distribution Layer (SDL) router process will enter a race condition and the CallManager service will terminate unexpectedly.  


When stationD process receives the ccNotifyReq message and there is no chassis interface (CI) associated with the StationCdpc process, then before we display the information in CcNotifyReq message, another check is made to make sure there is a valid CI to route pattern association; otherwise, it will crash the CallManager.  

Problem Symptoms

The CallManager service may crash and restart. The Cisco CallManager (CCM) trace file on the CallManager will indicate:
