TMM fails to start up with a semaphore error message similar to: Mar 13 10:55:28 slot1/bigip1 err tmm[12618]: 010f0001:3: semaphore already released: Resource temporarily unavailable
TMM is unavailable.
TMM is in the process of starting.
None.
During startup phase, if CMP packets are mis-directed to the wrong TMM, (e.g.: TMM0 sends "ready" to TMM1 and 2, but both arrive at TMM2) then TMM2 tries to release its semaphore twice, resulting in this error message. The fix is to correctly route packets.
