[c-nsp] Memory leak on in latest 12.0S on GSR? *Solved*

[Mack McBride]

We ran into a number of issues with the continuous writes killing the flash and other flash related issues.
The other issue we ran into was unacceptably long reboot times.
We also found the code conversion was unacceptably long.
Cisco highly recommends the PRP-3.
Our experience was that XR on the PRP-2 was less than stellar other users may have a different experience.

XR works just fine with prp-2

The GSR is still a solid supported platform, unfortunately the support contracts are completely
out of line with where the GSR fits in the grand scheme of things.  The newer PRP-3 cards are also
way over priced.  Unfortunately the move to XR code is next to impossible without moving to PRP-3 cards.

For the records:

the reason for my memory leak problem on latest 12.0(33)S was the
following configuration statement (for whatever reason it was there):

  aaa accounting update periodic 5

Removed this statement and reload once (to make the Check Heaps process
run quickly again) and everythings fine.
