DSM 7 / DS414: PMS 1.23.0.4438 Will Not Start

Plex Media Server NAS & Devices
1

Server Version#: 1.23.0.4438
Player Version#: any

DS414 was running PMS 1.22.3.4392 w/o issue.

Just installed 1.23.0.4438.

Now PMS will not start. I click on “Run” in the Package Center. PMS shows as running for ~30 seconds, then changes to Manually Stopped. Nothing is written into the log files.

This same thing happened with ARM v7 running DSM 7 a few releases back.

Possibly same issue has returned?

Logs attached, but unsure they show anything useful. Last entry in Plex Media Server.log is PMS shutting down before I installed the new version.

Additional Notes:

  1. Logs stored in /volume1/plex/plex_logs, not in default location.
  2. I stopped 4392 in Package Center, then installed 4438 on top of 4392. I did not uninstall 4392 first.
  3. Not my production PMS server. Using it to learn about DSM 7 & PMS on DSM 7. PMS has one library containing one movie.

Is this DSM 7 PMS installation one which was migrated from DSM 6 or was it created fresh on DSM 7 ?

3

Created fresh.

PMS not installed when on DSM 6.
Upgraded NAS from DSM 6 to DSM 7.
Then installed PMS on NAS.

thanks.

In your logs I see PMS shutting down several times and it does show crashing.

Would you mind turning Upload Crashes to Plex in Settings - Server - General - Show Advanced to OFF (Uncheck the box & SAVE) ?

By doing this, the scripting will move the crash dump file out to your Logs directory for easy retrievel.

When you see it, please put it in a ZIP file and upload that ZIP here.

We can put that in the debugger and see why it’s acting this way.
(Your logs are showing me it failing when doing network device discovery which should NOT happen)

I cannot change the setting as I cannot get PMS to run.

Can I access the necessary files via SSH? I’m comfortable with CLI, just need to know location, since everything has moved w/ DSM 7.

I could also fallback to 4392, change the setting, then install 4438 again.

Yes, you can make the changes to Preferences.xml

It will require using VI . Hope you’re ok with that. :slight_smile:

via SSH,
PMS stopped

cd "/var/packages/PlexMediaServer/home/Plex Media Server"
vi Preferences.xml

On that last XML line, before the closing />, add

sendCrashReports="0"

It will look like this when done

SomePref="Value" sendCrashReports="0" />

Save and exit

Start PMS & let it crash
Start it again & let it crash
Now you’ll find the DMP file in your Logs shared folder.

Edited the file, started PMS & let it crash three times.

The Crash Reports folder exists, along with subfolders, but contains no dmp files.

I found dmp files in /volume1/@apphome/PlexMediaServer/Plex Media Server/Crash Reports folder.

Great.

Thank you.

  1. I need to figure out why they didn’t move (start-stop-status should be doing that)
  2. I will pull them into the debugger tomorrow morning (it’s very late here)

Sounds good. Turning in myself (I’m an hour behind you). Let me know if you need any additional info.

Cheers

I did a lot of digging yesterday and, after a lot of fuss, was able to reproduce.

I tracked down when this occurred.
Next, I chatted with one of the engineers who did that work.
We think we know what it is.
What makes this strange is it didn’t fail in testing but does here.

Hopefully today :crossed_fingers: I’ll hear some news but Engineering is busy with meetings this week.

Thanks for the update. Appreciate you digging into things.

Let me know if I can help by testing an image on my DS414, etc.

Thanks

Mentioned on the other thread, but to close this one out as well.

Fixed in PlexMediaServer-1.23.0.4459-20536d6fc-armv7hf_DSM7.

I just loaded it on my DS414 and it loads/starts/streams OK.

Thank you to you and the rest of the team for jumping on this and getting it fixed so quickly.
