It appears to me that you are executing parent code in both the parent and the child.
I stripped your code down considerably and placed some print statements in there... Also added code so that it would work without the dbi stuff.
my @array = qw(1 2 3);
my $switch_ref = \@array;
for (my $count = 0; $count < @$switch_ref; ++$count) {
my $switch = $switch_ref->[$count];
my $pid;
if ($pid = fork) {
push @pids, $pid;
} elsif (defined $pid) {
print "Child: $pid\n";
} else {
die "Fork failed: $!\n";
}
}
foreach my $pid (@pids){
waitpid($pid,0);
}
print "parent: exiting.\n";

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
