This is how my logs look like:

How can I reduce these specific WARNING messages without reducing the log level? They’re so spammy that I a) can’t see anything else going on without extensively grepping and b) it’s filling up my disk to the point that 80GB of logs on the docker partition made my server go boom.

    Dunno, file a bug report up-stream? But I personally would just switch to error level only. You can always temporarily switch back in case you need to investigate something further.

    Oh and you should really delete old logs after a while (one month or so) as they can include a lot of privacy sensitive metadata.

      Good point! Sadly there are not a lot of options for logging, e.g. I’d like to disable the logging of IP addresses wherever possible.
