Server Version#: 1.41.6 Player Version#: NAS# TS251 QTS: 5.1.9.2954 I am finding that I am regularly (every six weeks, approximately) losing access to my Plex Media Server, internally and externally. I noticed it today while out and then came home and could not log in to the ip address of my PMS…

To be honest I am not entirely sure. My first instinct was that this was a problem with remote access and the need for a DDNS because I had been through that with Emby. However, now that I think about it I think it might be a crashing issue for the reason that when I got home I could not even access…

[image] sjkiss: However, now that I think about it I think it might be a crashing issue for the reason that when I got home I could not even access Plex inside the LAN. Correct. The problem here is that there is a piece of media which is causing PMS to crash. The only way I know of to find…

Ok I can probably tackle this. Some questions. How do you know that the crash was caused by a scan. Where do you see that in the logs? What scans would cause this? Just the sonic analysis? Or a general scan of library files? If we assume that I can’t fix this in the next two weeks should I suspen…

Answers: I do not definitively know the scan caused it. I can only deduce it crashed during the scan because I saw none of the other typical activities which follow music scanning. The nature of the log files looks very much like an OS crash (a string of nulls at the end of a file is the OS…

Thank you. I’ll work on this. Is there something being worked on at Plex to avoid a full crash? Or is it going to be solely on us to avoid corrupted files? I’m looking for the system logs of the NAS now.

[image] ChuckPa: Now diagnose by trial-removal (move somewhere PMS can’t see it) and re-run the analsys. Which is the best, quickest analysis to run to expedit the process? A library scan?

As we find these problems, with the help of sample files, we work to make PMS more robust and tolerate more. This is why finding that failing file(s) helps you and everyone else ( I will submit the sample to Engineering with the problem description for them to dive deeper and enhance PMS codin…

OK, thanks for all your help. I dont’ know if this helps your or not, but the files from those commands are here. what I find odd is that there are different time stamps between the directory list and the file list. Slightly modified files are attached here. I just deleted a bunch of rows of irrel…

Yes, it’s possible for directories and files to have different modification times. If Moby was the last directory but not the last group in the file list, I would use the file list and start digging.

OK, this may not be possible given my busy life. What kinds of analyses might trigger this? The “Analysis” menu option that pops up when you hover over the three dots of an artist, album or track? OR does it have to be the “media analysis” or “sonic analysis” as a scheduled task?

Yes, this is a workaround until you find the bad file
