I had an issue with one of my virtual servers and log rotation, that I found when trying to do a backup. The backup kept failing and pointed to a problem with the log rotations. I checked here and noticed that the virtual server name was wrong. I must have changed the name at some point and the name was not changed in the log file rotation. Probably one of those times I made changes outside of the system.
In any case I switched the incorrect name here and everything started working properly.
Maybe you just need to set up the rotation here or verify that the existing logs are actually listed properly or hasn’t been disabled?
