If you have an iRule that has FLOW_INIT stage execution, it is likely to result in random TMM crashes.
Traffic disrupted while tmm restarts.
iRule that has FLOW_INIT stage action in it. The FLOW_INIT stage iRule could be executed either because it was attached to a Virtual Server or configured on an AFM ACL Rule.
Do not use iRule with FLOW_INIT action. Other stage iRules does not cause this problem.
Memory allocation and release during iRule FLOW_INIT execution was not handled right in a specific scenario, which was corrected.
