jwkrahn was faster than me. Nevertheless some hints:

If you suspect an infinite loop, try to find out what is looping, e.g. with the following code: 

while((my $key,my $value) = each %hash)
{
   print "$key - $value\n";
   $count++ if $value==keys(%hash);
}

Then you would have seen that only the first element is accessed.

After that, you might want to comment out parts uncommon to you, e.g. by 

while((my $key,my $value) = each %hash)
{
   print "$key - $value\n";
   $count++;     # if $value==keys(%hash);
}

[download]
Now you see that the each works fine.

In a third step, google for "perl keys each" - and you'll find the exact reason and link as provided by jwkrahn.
