APMD process may crash intermittently (rare) when processing access policies.


APM end users cannot pass access policy, cannot login.


This rarely encountered issue occurs when any one of the following conditions exist: -- iRule is configured with 'ACCESS::policy evaluate'. -- NTLM authentication configured and ECA plugin is involved (for example VDI RDG). -- Kerberos authentication is configured with RBA enabled.



Fix Information

APMD no longer intermittently crashes when processing access policies.
