I did 2 things: Startet my program and make a System Core Dump and try to analyse it. (Seem that PING.pm have some problem to be load by the dynaloader especialy an hash %s is named a lot of times.)
I set up a network analyser (ethereal) then i startet my programm. If I use the tcp protocoll no package is generated. Maybe a problem between perl, ping.pm and my OS : AIX 4.3.3.
