I installed mono on a Centos 7 box with Apache 2.4 in order to serve 
aspx pages.
I had to use a patched version of mod_mono because the standard version 
2.10 doesn't compile on Apache 2.4. It works pretty well but in some 
request, I've not been able yet to discover the case, I obtain the 
following error:

System.Web.HttpUnhandledException: Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.Exception: Houston...

It seems very similar to the problem reported here 
https://bugzilla.xamarin.com/show_bug.cgi?id=16796 without any response. 
I checked the history of mod_mono 3.8 that enables Apache 2.4 support 
but I saw nothing related to this kind of problem.
Any hint about how to solve or diagnose better the problem?
Thanks in advance.
