hi,

The problem is that the delete($hash{$key}) doesn't seem to actually be deleting the hash

How do you delete undefined hash key?
if hash key is not present, there is nothing to delete. Don't you think so?
Peruse this:

use Data::Dumper; my $family={ father=>'foo', mother=>'bar',}; for(keys %$family){ if(!defined($_)){ delete $family->{$_} } } print Dumper $family; # print out your hash
but if you write this:
use Data::Dumper; my $family={ father=>'foo', mother=>'bar',}; for(keys %$family){ if(defined($_)){ delete $family->{$_} } } print Dumper $family; # print empty hash
I think you might have to look at your code construct again.

UPDATE:
Also in this:

my $file = sprintf('%s/%s/%02x.db', $qdir, $mypc, $i);
Hope, $qdir is decleared somewhere in your code?
