our ZoperServer (Zope-2.4.1-linux2-x86.tar, running on Suse 7.1) hangs up with the follwing message while accessing it via a Netscape Browser. Any hints ?

Then, Zope could no longer respond to HTTP requests. Do you lose one thread after the hand (look at the number of Python processes before and after the hangup).

If so, this would be a serious bug in ZServer - newly introduced not to far ago... Dieter
