Symptoms

tmm may hang and crash (killed by the switchover daemon, sod), when the Cavium hardware accelerator does not come back after the reset from the driver.

Impact

Traffic disrupted while tmm restarts.

Conditions

This is a rarely seen occurrence. It is triggered when the Cavium hardware accelerator stops working.

Workaround

Power cycling the system might correct the error.

Fix Information

The system now prints out an error message in the log file, improving the way tmm handles the failure.
