<p dir="ltr">That's the "well behaved" process. I'm looking for a solution at the kernel control level that can alter the list of ports the kernel manages for the aberrant process that hangs with an open port and dies leaving it open. It feels like a kernel bug to have an open port with no process attached. Closing a port with the owning process still running would be a useful tool for testing that process' response to a system failure.</p>

Uh, a port is only open if a process has opened it. Short of killing<br>
the process that opened it, your only option is dropping any requests<br>
to that port with an iptables rule.<br>
