Severity: 3-Major

Symptoms

In rare circumstance, when Policy Builder restarts continuously (in response to a different issue in which there are many shmem segments allocated and used by tmm), ASM-config Event Dispatcher memory usage grows uncontrollably.

Impact

ASM-config Event Dispatcher memory usage grows continuously until the device eventually fails over.

Conditions

In rare circumstances, Policy Builder restarts continuously (in response to a different issue in which there are many shmem segments allocated and used by tmm).

Workaround

Restart asm_config_server on all devices using the following command: killall asm_config_server.pl

Fix Information

ASM-config Event Dispatcher memory usage remains stable even upon multiple Policy Builder restarts.
