Symptoms

Occasional connections will be reset when using persistence. If tracking reset causes, the reset cause will be "Persist add entry not found."

Impact

Occasional reset connections. After 32 seconds of receiving traffic, the issue abates.

Conditions

This occurs only within the first 32 seconds of a tmm receiving traffic after startup. The client request further has to arrive on the exactly correct tmm on a chassis. This does not reproduce on non-chassis devices.

Workaround

None

Fix Information

Spurious resets of new persistent connections no longer occur.
