Connections leak, exhausting the memory over time and causing TMM to re-start.
TMM process re-starts causing traffic disruption. Low performance is also seen due to the high number of leaked connections.
Virtual server with port-preserve setting. Tunneled APM connections in a CMP environment (many TMM processes).
None.
The internal listeners that are created to forward the connections between TMM processes are now deleted when no longer needed, so new connections are not created, which prevents a memory leak.
