Upgrade failed for Synology - port 9981 already in use

Added by Greg Miller over 3 years ago

I just tried to update ffmpeg and tvheadend (4.3.20210612-29) on my Synology NAS. After the update the CPU stayed at 99% and I couldn't access the tvheadend page. I restarted the NAS but the problem persisted. I uninstalled both, restarted, then attempted to install but it failed with an error that port 9981 was either in use by another app or reserved by the system. Restarted and retried with same result. So first I would like to know how to clear the port, and second I hope th0ma7 ^ will be able to fix whatever caused this. For now no tvheadend...

Thanks for any help.

Edit: I don't see any suspicious application but I don't really know what to look for.

Suspicious application can be seen with 

netstat -lpnt

Thanks - that makes sense. I'm still not seeing anything suspicious.

There is possible conflict elswhere.
See other modules or config files.

RE: Upgrade failed for Synology - port 9981 already in use - Added by Marcel L over 3 years ago

I had the same problem.
My fix:

aktivate: Telnet + SSH in your Diskstation.

open windows cmd and write:
ssh your-admin-account@your-synology-ip -p your-ssh-port

get root:
sudo -i

then i have write:
cd /usr/local/etc

then i have write:
dir

there is a file named: services.d

i have checked what is in these file:
cd services.d
dir

i had the line: tvheadend.sc

Then i have remove it:
rm tvheadend.sc

And the installation was success.

I hope this helps. :)

RE: Upgrade failed for Synology - port 9981 already in use - Added by Greg Miller over 3 years ago

Yes, that did it. Thanks. The earlier output was through SSH so no problem doing it, other than I substituted "ls" for "dir". In fact I haven't found how to get into terminal from the DSM GUI so that is the only way I know.

It appears that the file tvheadend.sc was not removed by the uninstall script, or at least that is my best guess. I hope th0ma7 picks up on this.

Thanks again.
