Re: Is it safe to use log4cxx in multi-threaded environement?

A logger is should be thread-safe and can be used from multiple 
threads.  You do not need to request a logger for each thread.  If you 
do, you will just get multiple references to the same logger object.

The things you cannot do (without using socket listener) is to write 
have two appenders write to the same file or have two instances of 
log4cxx write to the same file.
