NPVR 5.0.1.200103 Always crashing

[Shep99]

Hello:

I previously tried out NPVR on windows, and just recently came back to playing with it on Linux! I'm running it on an Odroid MC1 ( Samsung Exynos5422 big-LITTLE octa-core CPUS with 2GB RAM ), with Ubuntu 18.04. 
I can install NPVR no problems, load my channel line up, heck even create a few recordings, and they sometimes work! But.... really often, unfortunately for no reason I can see, the service nextpvr-server just dies.... I could be changing a page in the web gui ( channels, to guide ), it crashes. Looking at recordings, it crashes, after a recording has completed, it crashes..... 

I must say I REALLY like the look of NPVR 5! And the fact that it's on Linux now, AMAZING!!!!! Would love to move to this from TV Mosaic, as TV Mosaic has issues recording a couple of shows sometimes, but can't after 4 days figure out why it keeps randomly crashing....

I've uploaded my log files to this post, and hope perhaps someone might be able to help me troubleshoot what the issue is, so I can start using this awesome version!

If it's any help, I had several crashed even just this AM ( Jan 28th, @ roughly 8:00 to 9:00 AM ).

Thanks all!

One thing I see in your logs is NextPVR could be starting before networking is available. I have suggested users check there logs and in the PreStartup.sh file and add a delay. My own is here
https://forums.nextpvr.com/showthread.ph...#pid530707 because I needed to wait for my USB device and network.

Your logs don't actually show a recording or crash so hard to diagnose. After a crash if you are running the deb install try

sudo service nextpvr-server status

might show some more information if not try

sudo journalctl > debug.txt

Look at debug.txt and if you don't see anything zip it up and post it here.

Hey Martin:

Thanks very much for the note, and absolutely that is a possibility about waiting for network. I tried to click on the link you sent, but I get the following error:

You do not have permission to access this page. This could be because of one of the following reasons:

1. Your account has either been suspended or you have been banned from accessing this resource.
   
   
2. You do not have permission to access this page. Are you trying to access administrative pages or a resource that you shouldn't be? Check in the forum rules that you are allowed to perform this action.
   
   
3. Your account may still be awaiting activation or moderation. (Resend Activation Code)
   
   
4. You have accessed this page directly rather than using appropriate forms or link.
   

Any chance you might be able to forward it to me via PM to test?


Thanks!

I updated the link sorry about that.

Awesome and thanks Martin, will test and report back. so far tonight, no lock ups but haven't tried out the Prestartup.sh script yet.

Hey Martin:

My instance kept crashing again tonight..... below is the output of the status:

I've uploaded the log batch also, hoping maybe someone can see why it keeps crashing.

Did you look in the journalctl output for anything more?

To me it looks like a segfault and the length of the last line of nrecord.log.3 is interesting. How long are the URL's that you are loading into NextPVR?
