Description (partial)


Active ACE got crashed with last boot reason as "last boot reason:  NP 1 Failed : NP ME Hung" after 2 to 3 hours of traffic run. I was having IP sticky and PAT enabled. Very high rate of traffic was hitting the box (120 k cps).

I did clear sticky database all, clear xlate & clear conn after each half an hour.


The issue happens when there is only one IP in the nat pool and very high rate of traffic is hitting the box.
