Hog 4 PC playback delay

I have a hog 4 PC system running v3.0.0 and I recently had to put it in a new computer. I have noticed that if the software is running for an extended time period (a couple hours) that playback becomes delayed. I'll press play on a main cue stack and the console will hold for a second or two and then "catch up". If I log off and log back in, there are no playback issues. It's like the console is buffering.

Any thoughts?
