This is some concurrency problem (it happens only on xsp startup) -
depending on system it can happen quite often or pretty much never.
Workaround is to try to run xsp again, or if you want to use it as web
server for real try to run it by some process manager which would
automatically restart it if it crashes (same goes for fastcgi server
from mono project)

Hi,
I was updating www/xsp(PR272997)[1], a Mono based
web server, and to test the port I run the samples
provided in the package as described in the INSTALL[2]
file.
Running this code causes a server crash, which
looks like a Mono issue. I'm not a Mono expert
so I wish someone can take a look ant tell me
if this port still usable on FreeBSD.
I try to run the same test with the current xsp
version, and I got the same error.
To reproduce the crash start the serven the server
and run the command: fetch "http://127.0.0.1:9000/";
