DTN.IQ Client Software Support » V4 Crashes Dec 8, 2005 01:50 AM (Total replies: 2)

Hi Jay,

> I assume the crash occurs when using your internally developed software?
Yes, that is correct.

> There is a documented memory problem in 4.0 using sockets to request numerous history requests.
That could be related - I am using using sockets to communicate with IQFeed.

> Take a look at the 4.0 documenation regarding the registry settings to change to turn on logging in IQFeed.
Ok, I will give it a try and get back to you if something comes up :)

> Also, is the crash in IQFeed/IQConnect or in your software?
The crash is definitely in IQConnect. After running for a few hours, Windows say 'IQConnect.exe performed a illegal operation and must be closed'. Once I click 'close' to terminate IQConnect, my application recovers normally from disconnection, IQConnect is reinstantiated and everything is fine again.

Thanks a lot! :)

DTN.IQ Client Software Support » V4 Crashes Dec 3, 2005 12:27 PM (Total replies: 2)

Hi there,

Since I upgraded to V4 I am experiencing periodic IQConnect crashes. I am pretty clueless about what could be causing it due the lack of debug information.

Here is the test cycle I was executing:

1. Application startup
2. Connect IQFeed
3. Request historic information for 175 symbols
4. Receive and process historic information for each symbol
5. Subscribe for streaming the same 175 symbols
6. Let it run 24 hours x 5 days

Unfortunately, the IQConnect crash is guaranteed to happen on the first three hours after all historic data is received. Because the crash is a 'hard' windows crash that invokes the 'this program executed an illegal operation' dialog, my application cannot recover from it until someone press the 'close application' button in the dialog.

Any ideas about what is going on? Is there anyway I can get IQConnect to spit debug information?

Thanks a lot!
