Fixed In:
16.1.0, 15.1.4.1, 14.1.4.4

Opened: Mar 30, 2021
Severity: 3-Major

Symptoms

High APM memory usage even in idle state when no traffic is flowing.

Impact

If idle state memory of APM is high then less memory is available for use during traffic flow and thereby can lead to OOM crashes and failover.

Conditions

APM policies configured with resource assignment agents with ACL policies configured. The idle state memory usage will be proportional to the number of resource assignment agents and ACL policies configured

Workaround

None

Fix Information

APM policy configured with many ACL policies no longer creates APM memory pressure

Behavior Change
