Description (partial)

NetTask failures are seen on 15454 and UTS chassis while running port scanning tools like Nikto and some STAT CD PSIRT tests. 

Analysis of the issue shows that while running the specific tests, there are way   too many TIME_WAIT sockets on the node. These sockets are consuming system  resources and resulting in failure to establish any more TCP sessions, creation of   new sockets and other operations that are dependent on using resources from the system pool.
