>Description:
	
	I am using libmilter api of sendmail to scan the incoming email.
	The package is home grown. It works fine on a system running
	freebsd-4.7-RELEASE. However on freebsd-5.1, every so
	often some of the perl process created by the milter are left
	in pipewr state. There is no process created by them that
	I can see. Truss on the process just hangs. Sendmail eventually
	times out on these mail and does a tempfail. but these process are
	stuck on the system forever and the number keeps on growing.
>How-To-Repeat:
	
>Fix:

	
	The only fix I have at this point is to kill these processes
	periodically.
