server crashing and I can't find the logs

[mchahn 20]

I'm running the emby server on my ubuntu 16.04 server.  It has worked well a long time.  I just did a "service emby-server restart" and I got a crash that looks like this ...

$ service emby-server status

I restarted my ubuntu server and the problem remained. I upgraded the emby-server using dpkg (3.3.1.0 -> 3.4.1.0).  The problem still remains. 

 

I tried unsuccessfully to find my logs.  I have no directory "/var/lib/emby-server".  The report-a-problem guide doesn't help.  

 

What should I try next?

Hi, this is something we've only encountered recently. The short answer is that the beta server has a fix if you want to try that. If you want to read more technical information about it, see here:

Thanks.

Thanks.  The beta version didn't fix it but I'm happy now using "nohup /opt/emby-server/bin/emby-server &"
