[Mono-list] multiple web apps with mod_mono

[Chris Turchin]

Hi,

until just recently, this morning in fact, I was able to run 4 web apps with
mod_mono concurrently and it seemed mostly to "just work". Since updating from
cvs today I have the following situation:

After an apache restart, the first app loads in the browser and runs fine.
However any attempt to start an additional app yields the following error:

Server error in '/blogx' application
Description: Error processing request.

Error Message: HTTP 500.

Stack Trace:

It seems to be irrelevant which app I open in the browser first, it will work,
and any further application will result in this error. My setup is mdk 9.1,
apache-2 2.0.47, mono, mcs,xsp, mod_mono etc from cvs (updated today)...

Here is my config according to server-info:

   Module Name: mod_mono.c
   Content handlers: yes
   Configuration Phase Participation: Create Server Config
   Request Phase Participation: none
   <snip>
   Current Configuration:
          MonoRunXSP True
          MonoWapiDir /tmp
          MonoUnixSocket /tmp/mod_mono_server
          MonoServerPath /usr/bin/mod-mono-server.exe
          MonoApplications
          "/gd-gallery:/data/web/gd-gallery,/Doogle:/data/web/Doogle,/tes
          t:/usr/share/doc/xsp/test,/blogx:/data/web/blogx"


and here is from my httpd2.conf:

LoadModule mono_module        /usr/lib/apache2-2.0.47/libmod_mono.so
MonoRunXSP True
MonoWapiDir /tmp
MonoUnixSocket /tmp/mod_mono_server
MonoServerPath /usr/bin/mod-mono-server.exe
MonoApplications
"/gd-gallery:/data/web/gd-gallery,/Doogle:/data/web/Doogle,/test:/usr/share/doc/xsp/test,/blogx:/data/web/blogx"

Alias /test /usr/share/doc/xsp/test
<Directory /usr/share/doc/xsp/test>
    SetHandler mono
    Order allow,deny
    Allow from all
</Directory>

* The other directory entries are the same , just other directories :-)

I had seen this error sporradically in the past after a httpd restart but then
it seemed to go away after a page refresh (<F5>). Now I can not get it to go
away at all... :-(

Is this a configuration problem? I know there were more changes to mod_mono last
week, maybe I missed something? Or should I file a bug report?

Thanks!
