Bug Tracker

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

Known Affected Versions:
11.6.0, 11.6.0 HF1, 11.6.0 HF2, 11.6.0 HF3, 11.6.0 HF4, 11.6.0 HF5, 11.6.0 HF6, 11.6.0 HF7, 11.6.0 HF8, 12.0.0, 12.0.0 HF1, 12.0.0 HF2

Fixed In:
12.1.0, 12.0.0 HF3, 11.6.1

Opened: Sep 28, 2015
Severity: 2-Critical


When the Application Visibility and Reporting (AVR) module is being used, the avrd daemon can consume all CPU. The avrd log will contain error messages similar to Semaphore DB_Publisher_ready is not set, for xxxx seconds


Avrd gets to 100% CPU and stays there even when no traffic is being passed, which will impact system performance


This can occur when using the AVR module.


Restarting tmm will temporarily mitigate this problem

Fix Information

Avrd is no longer susceptible to consuming all CPU indefinitely even when traffic is not being passed.
