I need to get daily data during the off hours. When I use a fixed size thread pool (50) and make requests as fast as possible I get a can't connect to the history socket message for all requests. If I throttle the requests it works. Is there a request per second limit?

I am using 4.2.1.4
Only one IQ32.dll
Java 6

Thanks,
David

There is not a limit in the code.

However, it is obvious that you have met some sort of limit...

In my experience, figuring out what is actually limiting the requests will probably be more difficult than simply modifying your code to ensure you do not reach the limit...

But if you would like to work with me in troubleshooting this, I am happy to do so. If you would like to send me an email to developer support with a simple app that duplicates the issue, we can start from there.
