I have reported a bug but noe activity shown, so I don't know weither
this is a bug or just a configuration error. The decription of the
problem from the bug report (
http://bugzilla.ximian.com/show_bug.cgi?id=69214 ) is (actually a

Description of Problem:
When I have more than one web application running on the same server using
mod_mono and XSP I cannot use multiline textboxes on more than one of them.
The other one fails (code 500, NullReferenceException).

Steps to reproduce the problem:
1. Create two applications using webapp-XML-config file on different
virtual hosts in Apache.
2. Add a webform using multiline textbox on both.
3. Run the two applications.
4: Restart mono, try both applications again, but the last one last time
first this time.

Actual Results:
The first application works, but the other one:
System.NullReferenceException: Object reference not set to an instance of
an object

in <0x00084> StateMachine:ExecuteState

restart mono, and try the other one, it works, then try the previos one,
does not work.

Expected Results:
Both applications work.

How often does this happen? 

Additional Information:
I'm using Apache 1.3.31 with mod_mono installed. The server has several
virtualhosts and I have created a config-file to XSP to run ASP.NET in /asp
on all hosts.

Have any of you experienced similar problems, any workarounds?
Anything wrong I might have done?
