Description (partial)

Symptom:
CLI session is closed (user logged out) after trying to get the output of a "show client summary". The output starts and we can see there are over 31,000 clients, but the CLI user is logged out before the output finishes.

Conditions:
- WLC with a huge amount of clients.
- WLC doesn't crash; the user that runs the "show client summary" just gets the CLI session closed.
- Once the user is disconnected, they noticed the following were the latest logs on the WLC:
