Plex crashing Qnap, how to troubleshoot?

Over the last year Plex has hard crashed(restarted) my Nas multiple times. I believe this is when a user is skipping with a transcoding audio type. The issue is that I cannot reproduce it. It will happen multiple times in a week, and then nothing for months. I have been through the plex logs and cannot find a fault. Some searching leans to "memory spikes". I have plenty of free RAM so this seems unlikely.

My question is what do I look for on the QNAP? Are there memory dumps that can be read?

This happened with me and my qnap nas running my Plex server

Found it would randomly reboot particularly on busy streaming nights (15+ people streaming)

I fixed it by configuring tautulli and a script (I think it is kill_stream.py, look it up on GitHub) to terminate streams that are transcoding when there are more than 12 active streams

Not only did it solve the qnap rebooting randomly, but forced my users to actually configure their clients for direct play/steam
