Description (partial)

When the PAT IP reaches more than 90% utilization, the time taken to allocate a
free port for subsequent PAT allocation increases exponentially.
The issue happens when there is only one IP in the nat pool and most of the
ports having been allocated along with a very high rate of traffic is hitting
the box.
