Description

This morning we found that all our TCP connections were being used. Wally and Beau are doing web development and their web app couldn't connect to ACNET. Doing some probing revealed that a Los Alamos employee's laptop was connected to acnetd 141 times! Cleaning the connections was tedious and restarting acnetd outright would have disrupted service to the local DPM.

I propose that acnetd processes handling TCP connections monitor the USR2 signal and terminate when they see it. This allows us to use "killall USR2 acnetd" to quickly disconnect mobile/web clients.
