Global Update consumes CPU but does not update anything.

Steps to reproduce

Trigger global/library update from /library or from /updates.

Expected behavior

Every entries in the library/global should get updated and logs of it should appear in the console.

Actual behavior

The update does something because it consumes 90-100% of a one CPU core but no updating is done. This is the only log i sometimes get:

but it does not stop the update from using the cpu core.

The webui never shows anything that may suggest a global/library update is running. I've got this problem since v2.3.2223 and i have already tried to restore library from a save. Manually updating any entry is working fine.
