Trying to locate a leak! What does anon mean for pmap?

Viewed 53381

I'm trying to locate where my memory has gone for a java process running in linux. Someone suggested I use pmap -x to see exactly what the memory is doing.

The output is really long but basically a good portion of it is a repeat of this:

00007fbf75f6a000    1016       -       -       - rwx--    [ anon ]
00007fbf76068000      12       -       -       - -----    [ anon ]

What exactly does this mean? Why do I have so many entries of this (4000+)?
