I have a hash (which varies in size) and am using it in the following code. 
foreach my $key (sort {$a cmp $b} keys %$hash) {
 if (scalar %{$$hash{$key}} > 2) {
  #do something
 }
 else {
  #do something else
 }
}

Which worked fine during my initial test cases. However, I just loaded a large sample of our real data into the system to run more tests and now I am getting the following error every 16th or 17th key:

Argument "2/8" isn't numeric in numeric gt (>)

sometimes the "2/8" is replaced by "1/8" .. and the error (warning?) repeats approximately 20 times (didn't count) before it continues.

No data is dropped/lost, it just displays that to stdout every 16th or 17th key.

what I am doing wrong?
