+Summary: xsp-1.1.18 on mono-1.2 throws random exceptions when serving web services requests
+
+80% of cases when I try to access web service method hosted on XSP 1.1.18
+on Mono 1.2 on amd64 architecture I get this exception:
+
+
+System.Exception: Error reading headers.
+

+
+The next 10% cases give correct output and the rest 10% just fails other
+way (I am not able to see how, yet).
+
+I can access 127.0.0.1:8080 with web browser without any problems
+(unfortunatelly, there is no web method without 'out' parameter, so I can
+not use test form easily, but I think this will work).
+
+The problem is when I access web methods using application written in PHP,
+so I believe there is a race condition somewhere.
+
+Please let me know if you need any further input which I could collect.
+
+There was some combination of XSP/Mono which worked relatively fine (some
+SVN around 1.1.17).
+
+Also, sometimes I get this segfault with first web method call (this bug
+was present in all previous versions):
+
+Listening on port: 8080 (non-secure)
+Listening on address: 0.0.0.0
+Root directory: /tmp/test/
+Hit Return to stop the server.
