Hi all, The following code is running on a high traffic site: 
open(file, "$mailclicks"); flock(file, 2); @recs = <file>; flock(file,
+ 8); close(file);
    $i = 0;
    foreach $rec (@recs) {
    $rec =~ s/\n//g; ($id,$description,$need,$received) = split(/::/,$
+rec);
        if ($id eq $formdata{'id'}) { $received++; $recs[$i] = "$id\::
+$description\::$need\::$received"; }
    $i++;
    }
open(file, ">$mailclicks"); flock(file, 2); 
    foreach $r (@recs) { print file "$r\n" unless ($r eq "" || $r eq "
+\n"); }
flock(file, 8); close(file);

This increments a tracking counter for use by another script. The problem is that the data file goes blank randomly. Other scripts access the file but I have isolated it to this snippet. I haven't been able to find a pattern or reproduce the problem myself. It generally takes 100 or so users before it happens. No corruption of the file along the way. I'm hoping this is a common problem in perl? Thanks much, Ian
