Config hot reloading not works when changes written often

[brandousov]

Hi!
Our API is listening for query DB and creates temporary paths for original MRLs. In the API log server listener successfully reload its config for first row 2021-04-28 01:00:02 OK! Config saved, server reloaded!, but not do the same for last row 2021-04-28 01:00:02 OK! Config saved, server reloaded!.

API updates query and config every 500 ms.
Server version 0.15.5, OS Ubuntu.

Can anyone help me with more control to file changed event listener/dispatcher?
