tmm core dump due to SEGFAULT.


The blade reboots resulting in failover. Traffic disrupted while tmm restarts.


System under load in network. Other conditions required to recreate this are unknown, but indicated a potential memory-handling issue.



Fix Information

The apparent memory-handling issue leading to the SEGFAULT has been corrected, so the tmm core and failover no longer occur.
