Understanding Devel::Leak

Question

Below is a piece of code I am using and its output.

my $handle;
my $enterCount = Devel::Leak::NoteSV($handle);
print "$date entry $enterCount";
<<<< my piece of code >>>
my $leaveCount = Devel::Leak::CheckSV($handle);
print "$date exit $leaveCount";

output:

1) 
Mon 11/10 02:34:55 entry 383852
Mon 11/10 02:35:03 exit 486726

2) 
Mon 11/10 04:00:31 entry 383852
Mon 11/10 04:00:39 exit 493216

3)
Mon 11/10 04:05:15 entry 383852
Mon 11/10 04:05:23 exit 493927

Every time I run my script the $enterCount value is same whereas the $leavecount values keeps on increasing. What dose this signify? Does it represent memory leak ? What exactly does it show?

Umm ... probably? Wouldn't you have to show the rest of your code for people to definitely say one way or the other? Even if this is a pretty much a duplicate question I still think it is a good one since there's no real "canonical" answer ... but see links below. — G. Cito, Nov 10 '14 at 19:48

You could check these SO references from @ether:

jkeroes on Github has a list of resources on perl memory leaks.

Devel::Gladiator is good for getting an overview of what is going on - you could probably modify your code to fit with the POD's Synopsis example.
