Bug#449287: /etc/init.d/exim4 gives "no such process" error when stopping exim4

[Frans Pop]

severity 449287 important
thanks

I've been seeing the same issue for some time on several systems,
therefore raising priority.

Here's the debug (set -x) output for the stop command during shutdown.
Hope it helps.

At first glance, the problem seems to be that first 'killproc' is being
called and later also start-stop-daemon. And then later there also a
'kill -0'...

Cheers,
FJP
