"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger
"Excellent datafeed !!!" - Comment from Arely

I'm consistently crashing IQConnect. This occurs after successful initialization for TCP/IP, enabling streaming news, and several headlines successfully received. My code also sends NNT messages and successfully receives news stories - one for each streaming headline, up to 200 or more before IQConnect crashes. Some initial screen captures are attached.

Hello fschroer, Can you give me a bit more information about how your program operates? From your post, I assume the following:

1) you have a socket connection to the Level 1 port as well as the lookup port.
2) You have streaming news turned on the level 1 port and with each headline that comes in, you make a NNT request for the story on the lookup port.

Is there anything else going on? Any other lookup requests/streaming data? If so, are they on separate socket connections? Is your app multithreaded? If so, what is being executed on which threads? What language is your app written in?

Can you email a copy of your app to developer support so that I can attempt to duplicate this internally?

Your assumptions are correct. I've sent a copy of my VS 2008 project (C#) to developer support, removing as much non-relevant code as possible, while still producing the error.

Interesting. I did not receive an email from you. Perhaps you sent it to the wrong address or it got stopped by our corporate spam filter. I have emailed you with more information.
