[PROBLEM] library update in progress

[arick]

Hate to spoil your argument, but

Code:

20200717 101346 thmcache: mp3: Zend media exception: File does not contain ID3v2 tag of supported version: v2.2

means what it says. The file in question doesn't contain a supported version of ID3 metadata. Nothing to do with moOde and certainly nothing to do with your issue. I have a number of test files in my system which produce the same message.

the system also automatically runs thumbnails update for the WHOLE music library.

Yes and this update runs fast on an system with reasonable file access times.

Dear Kent,
The file with unsupported tags couldn’t cause the update problem. This file existed when library was initially generated and was successfully parsed. It is in the library now.
 

Code:

Supercollider 07:02
Radiohead - Supercollider / The Butcher
The Butcher 04:41
Radiohead - Supercollider / The Butcher

If you don’t believe, I can delete this file and repeat all procedures for two days. Do you think it helps to solve my problem?

As to thumbnails update, is it necessary to update all thumbnails when the single folder was changed? Is it really necessary? Is it so difficult to set the correct parameters for thumbnails update procedure?
Regards
