Opened: Oct 10, 2018 Severity: 3-Major
The autodosd process consumes a lot of memory and continuously restarts. (The autodosd process is a control plane process which supports the BIG-IP AFM DoS Auto Threshold feature.)
The BIG-IP system continuously restarts.
Many virtual servers (e.g., 1,020) with dos-profiles attached, even there is no DoS vector enabled.
Set sys db dos.auto.threshold.learnalways to false. This sys db variable controls whether the BIG-IP system should learn/store traffic history and calculate the auto-thresholds when we are in manual-threshold mode also. The default is on (always learn).
The autodosd process allocates memory only when the DoS vector is enabled, so this issue no longer occurs.
