Hi,

What do you expect to synchronize? writing into the buffer or file?
The answer is also YES:
http://apache-logging.6191.n7.nabble.com/thread-safe-log4cxx-td32766.html

If you want you may output the thread id and see that for all your 100+
threads everything works:
http://stackoverflow.com/questions/9246677/c-thread-name-map-and-log4cxx
or
http://stackoverflow.com/questions/9082413/add-process-id-to-log-file-name-in-log4cxx
or
http://stackoverflow.com/questions/4286089/how-to-log-process-id-using-log4cxx-or-log4j

So, as a conclusion, a simple YES!
Alex
