Good evening,
My Plex Media Server has been crashing on a very regular basis (once a day or more often). In the event log, it is recorded as an error 0xc0000374 (heap corruption). Once I connected the WinDbg debugger, I was able to replicate the error and I hope the following runtime data will help you identify and fix it. If you need anything else, let me know and I’ll replicate it again and get you what you need. I’ve also attached plex logs as well
Here’s the message on the console when an exception happened:
Critical error detected c0000374
