We have been made aware of potential memory issues with the PP-Capture libraries. We are working on pinpointing the exact source of the issue and implementing a fix.

In the meantime, you should make sure you stop/restart your services every so often. Depending on the volume of jobs, you may have to do this every week of every other day. You could even implement an automated process to stop/start PPMessenger (by calling the Net START/STOP command as an external program) and having it run in the middle of the night, or whenever the system isn't busy.
