Troy,
You should also recycle the VontuMonitor.
Check the logs as well.. most of the time there is 1 large file or incident that is corrupted that is stopping the other events to be processed.
In some cases it might be best to Stop the Services and Copy the Incident files to another directory. Restart the services and make sure the system is still working.
Then copy the files Bit by bit back to the incident directory.. I would start with Newest first to see where the hiccup is.
Also What are the Specs of the Enforce server and have you tuned the settings for the to deal with the high or low Memory you have for the system?
Good Luck
Ronak
