Public bug reported:
This is a sister-bug to #1292567 which reports a similar problem with
asp.net 2.0. I have created two different reports, because the faults
manifests themselves very differently, depending on the asp.net version.
I have created an extremely small ASP.NET application (attached as a tar
file).
When I run that against the apache server on "saucy salamander", using
mono-server4, it runs just fine.
When I run it against the apache server on the current beta of "trusty
tahr", using mono-server4, the mono-server4 dies with a SIGABRT. The
client gets a "500" error and the mono process running /usr/lib/mono/4.5
/mod-mono-server4.exe disappears from the system.
Luckily there is a good description in the apache error log:

Debug info from gdb:
=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
So, as you see, the SIGABRT occurs in a basic mono runtime routine called from
the mod-mono-server4.exe
module. Of course, I cannot know whether the bug that causes the abortion is
in xsp or in basic mono. But
any search after the bug would start in mod-mono-server4, so I chose to file
the bug against that package.
I have the same bug on my company's larger ASP.NET application.
This report is not made from the "trusty" installation, that one is a
test installation without access to the net, so you don't get all the
stuff that apport would collect to you. Honestly, you don't need it to
reproduce, just grab a pristine trusty installation and try it!
However, a few important package versions:
libapache2-mod-mono: 2.11+git20130708.6b73e85-4ubuntu1
mono-complete: 3.2.8+dfsg-4ubuntu1
mono-apache-server2: 3.0.11-1
I am willing to offer any possible kind of assistance in fixing this
problem - my company had looked forward to upgrade to "trusty". But, to
be honest, I don't think you really need my help - the problem is so
trivial to reproduce, it ought to be pretty trivial to fix if you know
the ropes.
best regards
