[Mono-devel-list] Web Socket Code

[Tron Chambers]

Hi Dick,

Does this mean that the code in the message I was replying to from Colt 
Majkrzak doesn't reproduce for you either? If the above mentioned code 
sample also doesnt reproduce for you, I will try to make another minimal 
testcase.  I only notice this issue when I run the code for a very long 
time (on the order of days), running it for a couple of hours always 
works normally.  IIRC my code worked for days rather than 12-14 hours 
before dying with the same error in versions of mono from 6 months ago.

As far as the specifics go, the code in bugzilla is in fact using the 
same method calls (socket.Receive) as my code.  It is also functionally 
similar.

Thanks for the reply, I'd really like to help in order to get this issue 
resolved,

-t.c.
