[Mono-list] mono xsp exception

[jupiter.hce at gmail.com]

Hi,

I have a simple test program to regularily send string data to mono xsp web
server via ajax, the web server received it and returned the string
data back. It worked fine for 20 minutes, then the mod_mono server
threw exceptions in apache httpd error_log and the server stopped
response to client and cut down the connection (session). 

Although I assigned IsTermination=false the OperationContact, it still
threw exception with "IsTerminating is set to True" in the error message.

The exception did not seem from my simple test program, could any exmplain 
where those exceptions come from and what was it really means?
