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