Help: DVR Server panics - looping forever : RESOLVED

Channels DVR Server
#1

My DVR service is out of service. My setup was okay years. After encountering an issue, I rebooted my nuc. When viewing the admin page I see Channels is attempting to load the sources, there is a spinner. The source is an HDhomerun, I have no expectation that it will succeed because it has been way too long. I am not how troubleshoot.

Channels runs on nuc. Hardwired to router. Hdhomerun is hardwired. Both device are visible in Router app. Hdhomerun status page looks good. My nuc has internet access. I turned off the firewall even though port 8089 is open. But Channels app cannot connect. I tried my iPhone app and my firetv app.

I am lost on what to try next. Does anyone have suggestions?

See the Loading... and the highlight spinner keeps spinning. Well over 1 hour now.

I also tried to manually add the HDHomerun source. Channels remained in a Loading state.

#4

I am attempting to submit diagnostic logs. I've submitted logs previously. It was very quick. But, the submit is also taking a long time. I am not sure if the two issues are related.

BTW, The Nuc is running openSUSE Leap 15.3.

Here is a portion of the log. See the panic error. Anything to worry about?

I found the active log file and tailed. It hits the panic error and restarts. It is looping continuously.

Another piece of info. The backup file it is attempting to delete doesn't exist. Lots of 0 block files.

Your guide database is corrupted I think

Delete *.airings and *.groups in /home/jerry/channels-dvr/data

I deleted the files.It eliminated the panic error. But. it repeatedly wrote this to the log file.

The DVR Server says up long enough for me to submit diagnostic logs - I just submitted.

#11

Eventually the errors stopped. My TV is able to see the guide. I can watch recordings and shows. I think I am all set. Thank you!
