Following a restart, if apmd executes an iRule policy evaluate before its reinitialization is complete, apmd can crash.


apmd crashes and restarts, preventing end users from logging in.


If apmd restarts due to a crash or explicit restart command but tmm remains active, then iRule policy evaluate commands can reach apmd before it completes initialization and it will crash.



Fix Information

Now APMD has a more robust initialization process to ensure that it does not execute access policies from iRule commands before it is ready.
