Sorry to hijack your thread, just wanted to say thanks for the pointer. This was exactly my problem. Once I downgraded libmediainfo and mediainfo it is stable again.
Here’s what I did to tide me over until there’s a more permanent fix:
yum erase mediainfo libmediainfo
wget https://kojipkgs.fedoraproject.org//packages/libmediainfo/22.12/1.el7/x86_64/libmediainfo-22.12-1.el7.x86_64.rpm
wget https://kojipkgs.fedoraproject.org//packages/mediainfo/22.12/3.el7/x86_64/mediainfo-22.12-3.el7.x86_64.rpm
rpm -i libmediainfo-22.12-1.el7.src.rpm mediainfo-22.12-3.el7.src.rpm
systemctl start sonarr
I’ve blacklisted these packages in my yum.conf until a fix is found.
Cheers.
