Administrative operations which trigger a full reload of SSL cert, key, or CRL files can cause TMM to abort. TMM will miss its heartbeat, at which time it will be killed by sod daemon via SIGABRT.


Traffic disrupted while tmm restarts.


Configuration contains a large number of SSL certs, keys and/or CRLs.


Remove any unused SSL objects from configuration.

Fix Information

The system now loads the virtual IP addresses and associated SSL Certs/Keys in batches, so that TMM config load no longer exceeds its allowed CPU time.

Behavior Change
