Hey, any reason to run on loglevel 1? Other than that, this has been fixed in 33.0.1, which will not log the files related ones.

I think loglevel 1 was the default when I installed… I’ll try to upgrade to 33.0.1 though and see if that helps.

edit: Oh, 33.0.1 is not yet out - for now I’ll just use loglevel 2 :slight_smile:

4

I was going to say that :wink: But yea, loglevel 2 should usually be enough for production.

I increased log verbosity to tackle another issue I’m seeing and my log is filled with those entries as well.

Besides the obvious resolution of decreasing log verbosity I wonder why these entries are there. Does it mean config entries are missing? If yes: How to add them?

If no: Shouldn’t an issue be opened?
