[Mono-dev] Consistent failing in mod_mono / xsp / mono

[Ben Clewett]

Hi Mono,

I am using mono 3.0.0 with mod_mono 2.10 and xsp 2.10 on SUSE 12.1 on 
Linux 3.1.10 x86_64.

When starting my ASP code by starting Apache, all is well.

However when the process is re-spawned I get this exception more or less 
every time:

Exception caught during reading the configuration file:
System.MissingMethodException: Method not found: 
'System.Configuration.IConfigurationSectionHandler.Create'.

This is followed by the next exception, which will spin for ever.  This 
renders the server dead!

This can be corrected by a complete Apache restart.  However this should 
work without issue.

If there is anything anybody can suggest to solve this problem, please 
let me know.

Regards,


Ben
