Opened: Jul 01, 2020
Severity: 3-Major

Symptoms

The watchdog process in the BIG-IP ASM monitors terminates the admd process.

Impact

Restart of admd daemon. The restarts may be continuous. No stress-based anomaly detection or behavioral statistics aggregation until admd restarts.

Conditions

On some heavy load configuration process, such as version upgrade.

Workaround

For the case of continuous restarts, a partial solution is to disable admd during busy periods such as upgrades. To do so, issue the following two commands, in sequence, after the upgrade is complete: bigstart stop admd bigstart start admd

Fix Information

None
