I thought about that as well, but like I said, the size field in the table contains numbers larger than the ones I displayed. To be sure though, I altered the column to use BIGINT and the problem still occured (after I re-ran my program).

Here is the insertion code:

sub writeDB {

  # stuff ...

  $sth2 = $dbh->prepare( 
      " insert into files 
        ( client_id, path_id, file, size, ctime, mtime, atime )
        values
        ( ?, ?, ?, ?, ?, ?, ? )
      ");


  foreach my $path (keys %data) {
    my $pathInsert = qq`insert into path ( client_id, Path )
                        values ( ?, ? )`;
    $sth3 = $dbh->prepare($pathInsert);
    $sth3->execute($client_id, $path);
    $sth3->finish();
    
    my $path_id = $sth3->{'mysql_insertid'};

    foreach my $file (keys %{$data{$path}}) {
      my $size  = $data{$path}{$file}{size};
      my $ctime = $data{$path}{$file}{ctime};
      my $atime = $data{$path}{$file}{atime};
      my $mtime = $data{$path}{$file}{mtime};

      $sth2->execute( $client_id, $path_id, $file,
                      $size, $ctime, $atime, $mtime
                    );
    }
  }

  $sth2->finish();
  $dbh->disconnect();
 
}

Update: I did check to see if any of the files were negative before the perl->mysql code and they were at the time stat was performed (stat($_)).
