This seems to happen very infrequently. Symptoms vary from a simple TMM restart up to a blade reset. LTM log will show a sod message complaining about TMM heartbeats, followed later by SIGABRT messages from TMM.
Interruptions in data path processing. The interruption can be short for a simple TMM restart, longer for a full blade restart. Though these events altogether are rare, when they happen, it appears the simple TMM restart is more common than the blade restart.
TMM has not reported its heartbeat for a long enough period of time. The specific circumstances are unknown, but the issue has been seen with moderate-to-heavy system loads.
None.
