I have 2 programs: 1 client, 1 server. (simple, right?). I came across the RPC and MSG modules written in Advanced Perl Programming and put them to use. I have written a routine that looks like: 
sub checkuser {
    my $obj = shift;
    my $FN = foo::get_attr($obj , 'FIRST_NAME');
    my $LN = foo::get_attr($obj , 'LAST_NAME');
    my $USERS;
    my @USERS;
    my $line = "";
    open( 'USERS' , 'file' );
    while ( $line = <USERS> ) {
        chomp($line);
        my @parser = ();
        my $item = "";
        @parser = split( /,/ , $line);
        foreach $item (@parser) {
            $item =~ s/^\s+//;
            $item =~ s/\s+$//;
        }
        push (@USERS, \@parser);
        $USERS = @USERS;
    }
    close('USERS');
    my $i = 0;
    my $return_result;
    while ( $i < $USERS ) {
        my $FNT = $USERS[$i][1];
        my $LNT = $USERS[$i][0];
        if ( ( $FN =~ /\Q$FNT/i) && ( $LN =~ /\Q$LNT/i) ) {
            $return_result = 1;
            return ($USERS[$i]->[0] , $USERS[$i]->[1]);
        }
        else {
            $return_result = "User not found";
        }
        
        $i++;
    }
    return $return_result;
}

I had this code reviewed by others as well as reviewing it myself. It works fine when running on the client (the above sub is server code) as part of the client (i.e., inserted in the client program). When I put the server code back on the server, then call the command via RPC ($client->rpc('checkuser' , $obj), which is the client calling the sub from the server), the client hangs. I figure I am missing something very simple here. I've looked at the modules, and from what I gather, I am using it properly. The only thing that would make sense to me is that I am passing a blessed hash (which should not matter), $obj to the checkuser sub. Any help will be appreciated... Necos
