Description

In some situations pfSense can end up running the updaterrd script multiple times. This appears to be due to failing to kill previously running processes after making a change requiring it's restart.

On systems with a large number of states (>100K) this can result in a significant CPU cycles being used to service the scripts.

I can confirm this behavior. If the previous updaterrd script fails to finish, subsequent ones will still spawn anyway. This leads into an infinite feedback loop of CPU utilization until the firewall crashes or becomes unresponsive.
