> I have a strange issue.  I'm testing bad network conditions, where the cl=
ient looses connectivity to the server.  If the server is remote, and the c=
lient is inside my lan, and my lan looses internet connection, at least 1 t=
ime in 3 when the consumer gets created (or at least throws no error messag=
es), but doesn't actually consume messages off of the queue.  This leads to=
 no error message that I can catch, but the client never recieving another =
message.  For reasons that escape me, this happens FAR more frequently when=
 you run this program OUTSIDE of vs2005.  When I run through the debugger, =
or even through a "Release" build inside vs2005, this very rarely occurs.  =
Also, though this is much more minor, when the client does manage to reconn=
ect cleanly, I get 2 messages for each one I send, as if the consumer prior=
 to the internet connection loss isn't being deleted.  However, once I star=
t and stop the Connection, I get just one message recieved per message sent=
.  I'll show this in step form below.  Thanks for your assistance!

> Steps:
> 1.  Run a standard ActiveMQ server on a remote point
> 2.  Run a client inside your lan  (Fixing IP address and port for where t=
he server resides)
> 3.  Click "start" on the app, you'll see the messages your recieving star=
t scrolling down
> 4.  Yank the cord from your router that gives you an external internet co=
nnection
> 5.  After about 8 seconds, the text will tell you the disconnect occured,=
 then replug in the cord
> 6.  Click "start" again.  might need to do it more then once, as sometime=
s it's slow to get a good connection again
> 7.  At least 1 in 3 times after you click "start" it'll clear the text, b=
ut you'll never see another message, even if you "stop" and "start" again (=
leaving the cord alone)
> 8.  The rest of the time you'll see 2 messages appear for each one sent, =
after clicking "stop" and "start" again, you'll see normal behavior. =20
> I've attached both the client project I'm using for testing.  I was using=
 the stock ActiveMQ 4.1 server, only changing the IP Address of the TCP con=
nection to point to the correct address.
