This works fine when run interactively but hangs with a bunch of defunct children when the same user schedules an AT job to run the same script. Has anyone encountered this issue with fork() on RHEL AS 4? 
#!/usr/bin/perl
…..
my @children = ();
……
sub mysub {
my $pid = fork();
if ($pid) {
push(@children, $pid);
}
if( $pid == 0 ){
# child process code here
exit 0;
}
}
……
foreach (@children) {
waitpid($_, 0);
}
