I've seen this before and my problem was that I had two log4j configs printing the same lines on the log. Check your log file, it is probably duplicated there. If not, maybe you have something wrong on your logstash filter.

my log file ?

In fact i use a JBOSS handler to write on other host with TCP, i am trying to launch with command line, and with the windows service...

and the error seems to be when i launch service from windows service (with option config)
