Log overflow goroutine crash

Channels DVR Server Troubleshooting
#1

I think this may have been happening occasionally for the past week or so, but 2026.04.06.2028 has been crashing frequently. it does seem to happen when several recordings are happening, but sometimes it's just a couple. I can force the crash/reboot by Delete and Recreate Database

The log overflows, but here's the tail end of the latest one.

I believe this latest crash was triggered by deleting a scheduled recording for later tonight.

playback on gtv4k stopped and the cdvr log showed

Please go to Support -> Troubleshooting -> Submit Diagnostic Logs from the web interface of the DVR and let us know when it's been submitted so we can have a better idea of what was going on.

not sure how I looked everywhere but there.. lol server's always been rock solid! very familiar with androidtv's submit diag.
it's still gathering logs, comskip gets rather backlogged on my tiny n100 this time of night.

#5

actually the first attempt at this crashed the server, but it did not reset. I stopped the service, then restarted, and re- submitted diag
