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

Opened: Sep 28, 2015
Severity: 2-Critical

Symptoms

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

Impact

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

Conditions

This can occur when using the AVR module.

Workaround

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.
