[Mono-list] mod_mono Error: Blank Page with Apache / XSP

[Rote Hilfe e.V. - Stephan]

After a night shift and trial of many combinations I've no sollution
for the following Problem:

If I use the xsp server, the asxp Pages are served without problems,
but if I use the mod_mono only a white/empty page is delivered.

I used a packet sniffer and the result was "HTTP 200 OK" with an empty
page and content type text/plain.


I've tried mono .18 and .19 with xsp-0.2 and mod_mono-0.3 (binary and source
RPM)
in conjunction with httpd-2.0.44 (source and binary distribution).
OS is RedHat 7.3.

When trying to source compile the the ModMono.dll I get:

mcs.exe:1653: WARNING **: cant resolve internal call to
"Apache.Web.Request::[different functions]()" (tested without signature
also)
Your mono runtime and corelib are out of sync.

I've also tried the changes in the machine.config proposed by the FAQ.

Apache error log shows either nothing or (with mono .18):
GC warning: Finalization cycle involving xxxx


Maybe somebody could help me.
