Plex - Server error, issue with ld.so.preload

[Schwider]

Hey guys,

I’ve noticed my snapd Plex Media Server stopped working recently.

Doing some digging, sudo snap logs plexmediaserver gives me this result:

Does anyone know how to solve this issue?

This is a red herring … assuming you run this on a raspberry pi using the pi OS image, they add this awful ld.preload hack to their system (instead of properly patching the math functions of libc), but this has zero influence on the snap behavior … (you will find a lot of posts in here if you search for “libarmmem”) … to avoid the false positive error messages a suggestion has been made here:

LD_PRELOAD from host environment should be cleared when starting an app

Currently, if the host has an LD_PRELOAD environment variable set this is leaked into the Snap environment when starting an application. This means that the linker inside the Snap will attempt to load the library indicated by the host’s LD_PRELOAD and fail because the library is invariably not exposed through confinement. Therefore it is prudent for Snapd to clear the LD_PRELOAD environment variable when starting a Snapped application.

but since it only results in log spam and not in any functional issues, i dont think it has ever been prioritized …

Thanks, ogra. That makes things clearer. I’ll do some more research on the issue.
