Player Version#:

Hi there,
I think I installed it… read that some changes to a directory permission may be needed, but server still won’t start… figured out where the log files are and found this:
(thanks in advance; hoping to solve this so I can set this up in ubuntu and not have to run in windows)

seemed like plex server itself is using/listening on the ports?
$ sudo ss -tulnp | grep LISTEN

Shut down PMS
Check for threads hanging

ps aux | grep Plex

Kill them

Start PMS

found several processes. I tried to do kill -9 pid pid …
but they come back; the processes are restarting themselves?

also issued this > sudo service plexmediaserver stop
and then killed what’s left, but it still seems to restart it itself - but unsuccessfully, if I check the status

not that familiar with linux to be honest.

I’ve also tried restarting the machine. Power down and rebooted also.

If the main Plex Media Server process is not stopped, then that might kick off the others, thus why I asked you to stop that first

And the snip from the logs you provided, clearly shows that PMS was attemted to run twice

Reproduce, and then upload a zip with the whole logs directory

here are the log files zipped up

logs.zip (5.8 KB)

If there’s a way you can help me stop the server from restarting on its own. Then perhaps I can try to uninstall and start from scratch again?

When I did the install after downloading the package, I clicked on it and it seemed to install. But then through the browser, I saw that it didn’t seem to work.
So I got into the terminal and found the manual command to install the package again.

Anyhow, despite using the stop command:
sudo service plexmediaserver stop

I still find the plex processes running…
ps aux | grep Plex

I try to kill them with kill -9
but the processes keep restarting themselves…

thank you
