TMM might experience an infinite loop when selecting an available node for load balancing under heavy traffic conditions.
This causes a 10-second TMM heartbeat failure and a SIGABRT in TMM. The device goes offline and traffic processing is disrupted.
This occurs when the connection limit is specified for nodes, and there is heavy traffic.
None.
Connection limit on nodes now works correctly, and no longer causes tmm to loop indefinitely with heavy traffic.
