Using 'ss -o state close-wait' indeed returns PIDs of perdition processes.

Currently I did it the brute way: A cronscript running every 30
minutes finds all the PIDs involved and pkill them in one fell swoop.

It's not elegant, but it works...

The sheer number of close-wait connections is a cause of concern for
me, though... in that 30 minute period before the script gets
triggered, the number of close-wait connections reaches a high of
200-something.
