FYI, I worked through the logs and I think I found what the problem was. I was receiving the “Address already in use” error that was identified here: Random "Failed to connect to 127.0.0.1 port 32400: Address already in use" errors during scan. That led met to finding this article here: Plex Library Scans Initiate Hundreds of TCP_WAIT Sessions using up all available ports?. I didn’t understand how to apply the port changes but my logic was, if I can’t double the size of the ports, just split up my large TV library and that has worked well for the last 2 weeks, as I can space the scans of my TV libraries apart.
Can anyone provide some steps/screenshots on how to add more “ephemeral ports” as that seems to have worked for others. I would much rather have 1 library and I’ll happily re-import everything.
Thank you.
