Severity: 2-Critical


Per-request policy execution can appear to be slow during subroutine evaluation, and apmd appears to take a large amount of CPU.


Connectivity may be impaired or lost.


The per-request policy is using subroutine to execute an authentication related agent that is dispatched to apmd for completion. These typically involve authentication agents that interact with an external authentication server, such as LDAP, RADIUS, or AD.


Failover the high availability (HA) pair, or restart apmd.
