Thank you for your reply.

Problem is the main process is not supposed to exit. It just sits there
and waits for something to do, forks child processes and goes back to
sleep. I didn't mention that, sorry.

The original developer didn't bother to call Initialize- or
DestroyMagick(), that's my duty now ... Lucky for me, all the image
processing stuff happens in the forks, so from your reply I guess I
should just call both functions from there.

Thanks again,
Felix
