SUMMARY: Sizing /var/crash system with 32gb mem

It appears by default the system only dumps kernel pages. So sizing for the
entire memory is unnecessary .

     You don't need anywhere close to 32 GB.  When the system panics, it 
doesn't write the entire contents of memory to /var/crash upon bootup, 
just the "interesting" pages, which, as far as I can tell, is primarily 
the pages used by the kernel and it's data structures.

     So, if you've got plenty of disk to waste, you can make it 32 GB and 
be "safe."  However, I personally wouldn't size it more than 4-8 GB.
