Severity: 3-Major

Symptoms

TMM may not start when using more than 11 network interfaces with more than 11 vCPUs configured. You see the following log entries in /var/log/tmm: -- notice ixlv(1.1)[0:5.0]: Waiting for tmm10 to reach state 1... In the TMM log for that TMM, you can see that it is waiting for tmm0, e.g.: -- notice ixlv(1.10)[0:6.0]: Waiting for tmm0 to reach state 2...

Impact

TMM does not start.

Conditions

-- BIG-IP Virtual Edition (VE). -- More than 11 interfaces configured. -- More than 11 vCPUs configured.

Workaround

Configure fewer network interfaces or vCPUs.

Fix Information

Fixed a TMM startup deadloop stuck issue (when there are more than 10 interfaces and tmms/vCPUs).
