Symptoms

Inconsistent persistence entries across TMMs.

Impact

Inconsistent persistence behaviors.

Conditions

This occurs under the following conditions are met: -- intra_cluster HA configuration. -- node flapping.

Workaround

Add an iRule command to the PERSIST_DOWN event that deletes the persistence entry for this connection. One example might be: when PERSIST_DOWN { persist delete source_addr [IP::client_addr] } For more information, see SOL14918: Node flapping may cause inconsistent persistence records, available here: http://support.f5.com/kb/en-us/solutions/public/14000/900/sol14918.html.

Fix Information

An issue involving inconsistent behavior of persistence across TMMs is fixed.
