Last Modified: Nov 07, 2022

Affected Product(s):

Severity: 1-Blocking


Multiple ASM-config processes are running (more than 10) and consuming more than a GB.


The BIG-IP system might run low on memory and post the following message in /var/log/kern.log: Out of memory: Kill process 22699.


ASM provisioned. Repeated policy import via REST.


Restart asm - disrupting Restart asm_config_server.pl - non disrupting

Fix Information

We modified an operation to limit the number of ASM configuration processes. The operation now reuses processes instead of creating new ones, so the system no longer runs out of memory.
