Bug ID 857381: Avrd consumes 100% CPU within considerable time period after large configuration is applied

Last Modified: Feb 23, 2020

Bug Tracker

Affected Product:  See more info
BIG-IP AVR(all modules)

Opened: Dec 03, 2019
Severity: 2-Critical

Symptoms

When a configuration which contains very large number of elements (for example several thousands of virtual servers) is applied to AVRD, the thread that consumes configuration starts running on ~100% CPU. This continues until all configuration elements are processed. The process of configuration processing at AVRD can take approximately 30 min. After that, AVRD returns to its normal CPU consumption.

Impact

AVRD consumes considerable amount of system resources for relatively long time.

Conditions

BIG-IP configuration contains very large number of virtual servers, pools etc. For example when this was encountered there were 7302 virtual servers and 8944 pool members.

Workaround

Do not provision AVR or any of the modules that implicitly need it running: ASM, APM, PEM, AFM and AAM.

Fix Information

None
