As I have mentioned above, see at the "Haunted servers?" thread here on list. There are solutions etc for a similiar problem. This is all there what I know about this problem. (The RH Ticket has far less informations and not really a solution for it (sad :/ ))

In my particular case I'm interested, whether it can crash servers.
