When the system loads a configuration, SSL immediately reads any associated keys, certificates, and CRLs. This can take long enough that the watchdog timer fires causing TMM to restart.


TMM restarts.


Many SSL profiles are in use.


Use fewer SSL profiles.

Fix Information

Keys, certificates, and CRLs used by SSL are loaded on first use instead of when configured, which mitigates potential timeouts caused by SSL reading the associated keys, certificates, and CRLs for many SSL profiles.
