Description (partial)

ccm service memory continues to increase until it reaches its max VM size at which point core dump occurs. 
Core dump backtrace will show symptoms of memory leak.

Seen on busy multi-node clusters with multiple call processors (appx at least 2 nodes with about 5000 phones on each), where call flows may involve call control moving between the nodes, such as transfer across nodes.
In these conditions, we would see about a 1-3MB increase in memory for every 3-4 hours of the business day. 

Found initially on 9.1.1.
