Hi,
Your application depends on the Thread.Interrupt () method which is not
implemented in mono. In previous versions, it did nothing, in later versions it
throws a NotImplementedException to alert users to the fact that it is not
implemented.

Dear all,
I have been developping a bunch of client/server applications for my
research. In a nutshell, the client is tasked to contact the servers around
the network, have them perform a bunch of tasks, retrieve/archive the
results, and close the connection. All the application are developped in C#
.NET; the client application typically runs on a Windows XP type machine
whereas the servers run on Ubuntu Linux hosts (both Breezy Badger and Dapper
Drake). The linux hosts all have custom kernells to 'enhance' performance.
So far I have developped and tested my applications on a computer running
Ubuntu Dreezy 5.10 and mono-1.1.8-3 (default version available with Breezy),
and everything works fine. However, if I do run the applications using
another version of mono (1.1.13-6 [default version of Dapper) or 1.1.14), my
applications crash. Apparently, this is due to some event within my
applications that is not handled???? Here is a sample of what is going on
using version 1.1.8-3 in the first instance then 1.1.14

I could live with a warning but not with a problem that stops my
applications from cleaning/closing the underlying sockets and so on. As you
can see my applications are configured to accept one connection at a time,
hence the client comes back from the next batch of task it gets rejected
puting my experiments in jeopardy. Please note that the exact same error
occurs in 1.1.13-6 (Dapper Drake), and also note that once 1.1.8-3 is
installed on Ubuntu Dapper Drake the application demonstrated in the above
WORKS!
Now, I admit the CMCS dlls that you see in the above have been developped
by yours trully. They allow using TCP connections transparently, and ONE
event is used/raised to trigger the connection pool management (without this
features my programs don't clean their connection pool and thus I can easily
be DDoS'd ). They also force developpers to respect the various protocols
that I defined. But frankly, I don't see why my stuff would work on
mono-1.1.8-3 but not on other versions, such as 1.1.13 and 1.1.14 .
To make sure that this is not due to the compiler, LinuxSlaves have been
compiled under both Windows XP (using Visual Studio 2003) and MonoDevelop...
but not that does not seem to change anything.
Honnestly, I don't have the first clue about what is wrong! However, my
fellow researchers and I would like to have this fixed for all version of
mono because otherwise that will force us to "freeze" our test bench which
could become problematic in the long run.
I do hope that there is a simple fix to this.
Thanks a lot.
