3.4.0.0 crashing SEGV

[frankw 8]

So took the plunge and upgraded from most recent stable (3.3.1?) to 3.4.0.0...

 

Firstly, there is some issue with the unit file being masked after install, not quite sure what. Seemed to be ok after "systemctl enable emby-server".

Now running into a random crash, logs attached. Also got this output from systemd:

Seem to be able to trigger it just by clicking on some media that does not have images displaying in the Web UI.

Can you attach the emby server log as well? Thanks.

[frankw 8]

Sorry attached, missed pressing the button

[frankw 8]

Another log prior to crash.

That's strange. Nothing obvious there. What were you about to try and play?

[frankw 8]

Hey Luke, it can be reproduced any time you open a new file that does not yet have a thumbnail. I have tried opening multiple TV episodes via the WebUI of different types/shows/codecs, and it segfaults immediately if they are new, but anything downloaded prior to the upgrade works fine.

Was fixed by removing all configured library locations, re-adding from scratch and doing a full library scan.

[Luke 37193]

Interesting, thanks for the feedback. Did you attempt to migrate from the legacy installation to this?

[frankw 8]

No, I uninstalled the old opensuse version as per some notes I read on the forum, and then installed the new deb package from github as per the instructions on the website.

Hi,

 

I have exactly the same behavior, Each time I click on a file without a thumbnail, Emby exits via Segfault, nothing on embylog, only a message in syslog

 

May  4 08:57:55 kernel: [66067.166100] EmbyServer[20501]: segfault at 0 ip 00007fc653c32ee0 sp 00007fc54dff81b8 error 4 in libc-2.24.

for your information, I was on the legacy system until version 3.3.1 and to install 3.4.0 I moved to the new installation system.

I have uninstalled emby, purge it and delete /var/lib/emby-server.

after installation via dpkg connection via http, enter my key, installed the backup plugin, and restore the last backup, and do a full scan.

Do I have to remove all configured locations, re add them and do a full scan again ?

 

Thanks,

That's what worked for me

[fkp 3]

Not for me not sure that the backup is compatible between the legacy install and the new one.

I had to purge again emby, and limit the restore from the backup plug-in to the strict minimum (users only) and create again the configuration and the libraries.

Seems ok now.

After upgrading to 3.4.0.0 on my Ubuntu 16.04 server, Emby would just die. I discovered that it was dying while scrolling through the library, in particular, when there was a boxed set in the list. Also, when I clicked on "Collections" in my home screen, Emby was dead immediately. Scrolling "TV Shows" didn't cause this issue. What fixed it for me was to disable "Library/Display/Group Movies into Collections." Then I removed the "Auto Boxed Sets" plugin, restarted Emby and let it complete a scan. After verifying that I was able to scroll through my whole list of movies without failing (and without grouped movies), I checked the "Group Movies into Collections" box again and added the Auto Boxed Sets plugin, restarted Emby and let it complete a scan. Life is good again.

[fkp 3]

I had to remove auto box sets and remove collections, if I check or not "Group Movies into Collections" emby crashes each time it displays collections.

upgrade 3.3.1 to 3.4.0 is a real pain for me, install uninstall purge scan crash scan crash, i'm fed up with emby

Thanks to the help of another user I think we've narrowed this down:

 

https://emby.media/community/index.php?/topic/58592-3400-hanging-during-library-scan/?p=574157

 

It is occurring due to having added a collection to itself, and the server gets stuck in a loop trying to resolve the items for the collection. There are other similar circular situations that might cause this, such as having two collections, A and B, and adding A to B and B to A.
