That zombie process is a good indication that something isn't right. The parent process of 1081 is probably 1080, so this custom perl filter isn't managing its child processes right.
Or, if it's another filter started by courierfilter, it died. That's not good. During the orderly shutdown, courierfilter stops one filter at a time, and then waits for its process to terminate. It does not expect that the process that it started has already been terminated. That will definitely bollox up the "courierfilter stop" routine.
