NextPVR refuses to start

[ballfam]

After running fine for several years on the same system, my nextPVR server crashed and is now refusing to start. systemctl status is reporting:

Code:

● nextpvr-server.service - NextPVRServer
     Loaded: loaded (/lib/systemd/system/nextpvr-server.service; enabled; vendor preset: enabled)

Anyone able to interpret the stack? Is there something up with one of my config files?

Thanks

OK, weirdest thing....so I log in as root and go to /opt/nextpvr/shell, and then:

Code:

./server.sh start
Starting server..Done. PID=7541

And now it's running, but everything is empy, no devices, no channnels, no recordings....

So, I stop it:

Code:

./server.sh stop
Stopping server..Done.

And then:

Code:

# systemctl start nextpvr-server.service

# systemctl status nextpvr-server.service
● nextpvr-server.service - NextPVRServer

And now it's running perfectly fine.

I have no idea what happened here, but problem solved.

One of your IPTV channels is corrupt and seems to be able to cause a server crash when you record from it. The logs might show which one.
