[jira] Created: (AMQNET-43) Strange Disconnect issues with .Net and
VS2005
Strange Disconnect issues with .Net and VS2005
----------------------------------------------
Key: AMQNET-43
URL: https://issues.apache.org/activemq/browse/AMQNET-43
Project: ActiveMQ .Net
Issue Type: Bug
Components: ActiveMQ Client
Environment: Windows XP, VS2005, grabbed head of .Net client as of 2/12, useing ActiveMQ 4.1 on server
Reporter: James Stanton
Assigned To: james strachan
Attachments: JMSDisconnectTest.zip
I have a strange issue. I'm testing bad network conditions, where the client looses connectivity to the server. If the server is remote, and the client is inside my lan, and my lan looses internet connection, at least 1 time in 3 when the consumer gets created (or at least throws no error messages), 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 reconnect 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 start 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 the server resides)
3. Click "start" on the app, you'll see the messages your recieving start scrolling down
4. Yank the cord from your router that gives you an external internet connection
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 sometimes 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, but 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.
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 connection to point to the correct address.
