Thanks, I think I understand, it's not the handle but the driver that causes problems?

Unfortunately, system() doesn't help because I need each job to be executed in paralell and I don't want to sit around and wait for each one of them.

I have tried rewriting &child() like this: 

sub child {
  my $job = shift;
  exec("perl", "child-script", $job);
  exit; # Just in case
}

...but DBI still crashes with the same message.
