Yes, Sir! To isolate the error I disabled the DBI and even the LWP... so this script do nothing but printing ... 
#! perl 
use strict;
use threads;
use Thread::Queue;
use LWP::Simple;
use DBI;

sub fetchNParse {
    my( $Qin, $Qout ) = shift;
    while( my $uname = $Qin->dequeue ) {
        #my $content = get $uname;
        #my @bits = $content =~ m[....];
        my @bits=qw(pizza2 steak2 chicken2 burgers2);
        print " $uname 1\n";
        #$Qout->enqueue( join $;, $uname, @bits );
        $Qout->enqueue( $uname );
    }
    $Qout->enqueue( undef );
}

our $THREADS //= 16;

my $Qunames = new Thread::Queue;
my $Qrets   = new Thread::Queue;

threads->create( \&fetchNParse, $Qunames,$Qrets )->detach for 1 .. $TH
+READS;
#my $dbh = DBI->connect( ... );
#my $unames = $dbh->selectcol_arrayref("select uname from event");

my @unames = qw(pizza steak chicken burgers);

print "a\n";
$Qunames->enqueue( @unames );
print "b\n";

for( 1 .. $THREADS ) {
    while( my $ret = $Qrets->dequeue ) {
        #my( $uname, @bits ) = split $;, $ret.
        #$dbh->do( insert stuff );
        print "2\n";
    }    
}
#$dbh->disconnect;
