Symptoms

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

Impact

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

Conditions

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.

Workaround

NOne.

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.
