Hi, Monks!

I need your help again. My question is why i have zombies process when i run my program?

Zombies looks like so:

 3614 pts/1    D      0:00 /usr/bin/perl /root/USS/uss.pl
 3616 pts/1    D      0:00 /usr/bin/perl /root/USS/uss.pl
 3617 pts/1    Z      0:00 uss.pl <defunct>
 3618 pts/1    Z      0:00 uss.pl <defunct>
 3619 pts/1    Z      0:00 uss.pl <defunct>
 3620 pts/1    Z      0:00 uss.pl <defunct>
 3621 pts/1    D      0:00 /usr/bin/perl /root/USS/uss.pl

Here is part of program:

foreach my $row (@$sections) { if (my $pid = fork) { push @pids, $pid; } else { open BIDS, ">>", $CONFIG{BIDS_FOLDER} . "{currentsite}_" . $row->[ +0] . ".svd" or die "Could't open bids file!"; flock(BIDS, 2); print "$site_id, $row->[0], $row->[1]\n"; $found += search_bids( $site_id, $row->[0], $row->[1] ); flock(BIDS, 8); close BIDS; exit; } } for (my $i = 0; $i <= $#pids; $i++) { waitpid($pids[$i], 0); }

In search_bids sub i'm printing into BIDS and doing some LWP::UserAgent (getting pages and parse it) stuff.
