Hi all,

I have an Embperl page that uses a custom module which has code that calls
an external perl script via fork. This script takes a considerable amount of
time to run and I need it to just run in the background. I've gotten it to
work but I'm noticing that I've got zombies once the processes complete
until I restart Apache.

Here's the code:

   my $pid;

   unless ($pid = fork) {
      local($SIG{HUP}) = 'IGNORE';
      local($SIG{USR1}) = 'IGNORE';
      local($SIG{USR2}) = 'IGNORE';
      exec $command;
      die "no exec";
      exit 0;

Am I missing a signal or something to run this command as an entirely
stand-alone process?
