Description

When starting the queryable state servers the following is printed in the logs both the NetworkEnvironment and AbstractServerBase are logging events about it.

I suggest to remove the logging message from the NetworkEnvironment. Furthermore i think it would be good to use a non-static logger in AbstractServerBase to better differentiate between classes.
