increasing latency during a (recording) session

through the years I've experienced this: you start a sessions with DAW X and audio interface Y and MIDI interface X. You made the best buffer, samplerate etc. settings to have as little audio and/or MIDI latency as possible. I do understand the concept of latency.

However, the one thing I could never solve is the fact that latency tends to *increase* during a session. The only solution for that for me has always been saving the session, rebooting the computer and start freshly with the saved session.

My main question is: what is causing the latency INCREASE during a session? Example: I record let's say an Omnisphere track and play it with an external midi keyboard. After a few recording takes (not adding tracks, but re-recording the same track a few times), latency has clearly increased, so much that I have to reboot. Why? (I am using the newest MacBook Pro with 16GB RAM and a MOTU 828X audio interface)
And is rebooting the only "solution" to bring it back to it's "start" latency? Or are there better ways? This puzzles me for years now.
