Orphaned livetv buffer files

[snagglewest]

Sub,
I updated to 5.1.4.210802 when it came out and everything seemed good until the last few days when I started having strange incidents where live tv would freeze up using Kodi.  After about 30 seconds or so it would dump me back to the channels list.  I’m running NextPVR in a Ubuntu 20.04 VM with a 60Gb system drive and recordings go to a NFS share.  livetv stays on the VM.  This setup has worked very well since V5 came out.

Long story short, I found this error in the logs “Unexpected error writing to OutputSink: System.IO.IOException: No space left on device”  I tracked down the problem  to the livetv directory being full of orphaned .ts files.  It was so full it was also causing problems with the logs too.  The first set I tried to grab was completely blank and the second set as you can see shows the error.

Deleting the orphans solved the problem for now.  I wanted you to be aware and ask if you might be willing to incorporate a small routine to delete any orphans occasionally?  I know it’s supposed to do this anyway but obviously something is going sideways occasionally.

Thanks

Before cleaning the live*ts files out did you look at the dates of the temp files to see if it is a new issue?

Have you got a set of steps that reproduces the issue?

The orphans were from various days but I did notice some back as far as 8/4.
No sub, I have no idea how to reproduce it. This is something new that just cropped up and I didn't even realize it until today when I did a deep dive to find the problem.

I haven't spent much time trying to figure out the exact sequence of events to recreate this on demand but I found some more orphans when I just checked the disk space and noticed it loading up higher than what I would expect.

USA-HD-23 series was from earlier this afternoon via kodi.  That stream was stopped via a kodi using the normal stop button.  The USA-HD-24 is the new stream stated a short while ago and it's still running as normal.  I don't see anything glaring in the logs but then again I don't really know what I should be looking for.

I've wasted way too much time trying to reproduce this problem on command but I've not had any solid results.  At that end I've decided to just take the easy way out and create a PostUpdateEPG script to delete the orphans each day when the EPG update runs.  In short it just deletes any .TS files in the livetv directory that are older than 300 min or 5 hours which should exclude anything in use.  It's not elegant but it works and maybe it'll help someone else who stumbles upon this post in the future.  

Code:

#!/bin/bash
find /home/npvr/recordings/livetv/*.ts -type f -mmin +300 -exec rm {} \;
