Regarding cleaning up existing empty directories, can we at least remove the ones that are older than x days?

good idea, will do

@fabpot cleanup added. I considered directories as stale after 7 days. wdyt?

Great! Thank you.

Thanks, unfortunately it is somehow not working for me. Are old files removed only on "clean" shutdown of the server? I cannot gracefully stop server withserver:stop since#397 and while force shutting down with Ctrl+C there is some attempt to remove logs, but it almost always fail

Error message says that file is used by another process and cannot be accessed

AFAICT this error is not related to this PR and is only related to#397 (on which I didn't had the opportunity to work so far)

Yes, my question is not about this error, but on conditions required for cleanup process to be performed - if it requires "clean" shutdown by callingserver:stop or if should be performed on any type of shutdown - like Ctrl+C, stopping process via Task Manager, issuingkill command with pid etc.

On any shutdown. But your error happens during the shutdown process and things are not necessarily linear in Go so your error might end up stopping the cleaning process early on

@srsbiz see#569 for an attempt to improve this for you (won't fix the initial error)
