in reply to perl bug? illegal seek with dup and many filehandles

while you fd limit may be sufficient you may have a ulimit in the shell that the script is called from, run
ulimit -n
and if it's too low run
ulimit -n $bigNumber

    ulimit -n 100000 has no effect - it changes the same thing as the setrlimit() call
