Hi there,

first, I want to introduce myself. I am working at the Johannes Kepler
University of Linz/Austria. Our Department does the web-things.

We are on Zope and recently we started to use ZEO and Pound.

Now a problem came up. When selecting a lot of Objects (about 85) in ZMI
and pressing "Copy" I get this:

"""
Bad Gateway
The proxy server received an invalid response from an upstream server.


Additionally, a 502 Bad Gateway error was encountered while trying to
use an ErrorDocument to handle the request.
"""

Our configuration is like this:
Apache - Pound - ZEO-Clients - ZEO-Server
Apache does Virtual Hosts and Url-Rewriting

The error is still there, when I reduce the number of ZEO-Clients to
one.

When I pass by Pound (Apache - ZEO-Client - ZEO-Server) the error does
not come up also when I pass by Apache (Pound - ZEO-Client -
ZEO-Server).

Could there be a problem between Apache and Pound with long Requests?

Here is my pound.cfg:

User nobody
Group nobody
ListenHTTP *,9080
ExtendedHTTP 1
UrlGroup ".*"
BackEnd 127.0.0.1,10120,1
EndGroup

Best Regards
