Emby 3.2.36.0-1 crashing with ImageMagick 6.9.9.25-1


Recommended Posts

Hello, 
 
Not entirely sure if this is an Emby issue or a ArchLinux/ARM issue, but I'll throw this here just in case someone else runs into this. I just did the system update today. It's run without issue (until today) for about a year now. 
 
It looks like emby-server (emby-server 3.2.36.0-1) crashes after an upgrade of imagemagick (6.9.9.25-1). I had to rollback to the previous version of imagemagick (6.9.9.23-1). I'm running this off ArchLinux on a Raspberry Pi (Linux alarmpi 4.9.66-1-ARCH). 
 
Here's the error that came up:

It *looks* like this was causing mono to coredump:

Rolling back to the previous version of imagemagick got emby-server back up and running, but I'm not sure as to the solution moving forward. 
 
Anyway - if anyone has any suggestions (aside from rolling back)...
 
Thanks,

hi @@CLM73, you should probably roll back for now. We are in process of moving away from both mono and imagemagick and onto microsoft .net core and the skia image processor. 

 

We've already completed this for arch linux x64 and in the near future will have arm as well. Because of that, rather than try and trace down whatever is happening here I would just suggest rolling it back for now to get yourself back up and running. Thanks !
