Never had issues before with my server (2-3 years)...until an unfortunate Hardware failure 3 weeks ago and inevitable Re installation of OS and Plex Server. Luckily right before the wipe, i managed to backup the Plex Server directory (Where DB resides) and copy the files back, post re-installation, it recognized the "orphan" server and adopted it :)
Unfortunately, since that fresh install, i get s PMS crash once or twice a day and i have no clue why. nothing really changed in Library structure, even drives are labeled the same. Locations are the same.
I've even updated the server version (so 2 iterations, same results)..
One exceptional change: Not all TV metadata gets refreshed properly...
