The first each reads one key/value pair from the hash and then the next each continues where the first left off and reads the next key/value pair from the hash.

You probably want something like this: 

if ( keys %ip_discover_count )
{
    my $seedFileName = "$CC\_discover.txt";
    open my $SEED, '>', "$dir/$seedFileName" or die "Cannot open '$dir
+/$seedFileName' $!";

    while ( my ( $key, $value ) = each %ip_discover_count )
    {
        $ip = trim( $key );
        my $snmp_read = trim( $ip_discover_snmp{ $key } );
        print $SEED "$ip\t\$snmp_read\n";
    }
    close $SEED;
}
