Mmm, I have no idea.

Maybe Dieter or Chris or the other experts?

sure I am not one of the experts :) but anyway:

Well, but the Zope then crashes for 2 sek and is then up again. Other pages on the Zope server seems to work fine.

Does Zope have a auto-recover function? Is that what I'm seeing?

I get that message (except for /admin/submit_handler of course) if I have a VirtualHostMonster and my Zope is not running.

Dear List

Platform: FreeBSD 4.6, Zope 2.5.1, CMF 1.3, Apache

Apache is in front of the Zope server.

Error message: The proxy server received an invalid response from an upstream server. The proxy server could not handle the request POST /admin/submit_handler.

Reason: Document contains no data

I get similar errors when there is an ugly exception in the ZPublisher, e.g. when trying to send HTTP-Headers in unicode. If the exceptions happens "very late", this seems kills the thread -- Zope closes the connection instead of sending an error page. If this happens, there is an error message in the var/stupid.log - if Your problem is similar, You should find some there. However my Zope usually run out of threads after a while, as it did not fork new threads to replace the killed ones. Maybe Zope behaves different, if not started with an '-t N' option as in my case? This phenomenon happened 2.5.1. Sorry but I cannot reproduce it the with 2.6.0, as my way to produce a "late exception" has been fixed in 2.6.0. Clemens

...

Problem is that the error occurs "some" times. It is *not* browser dependt.

Any ideas?
