IQFeed Developer Support » History Errors - no response and hung IQManager Aug 13, 2005 08:39 AM (Total replies: 27)

Hi Natalie

The problem is still there. Out of 10 attemps to process the data, during 6 attempts, 1 thread remained hung due to createdispatch (iq_api) never returning, in which case, the remaining thread will succeed in processing the symbol list without iqconnect hanging.

During the 4 times both thread successfully established a connection, iqconnect hung after processing 16, 44, 27 and 47 symbols. All requesting 22 days of data.

The problem with createdispatch not returning was also present in 2.3.0.7 although happened a lot less often.

If you want, contact me directly and I will provide you with a program and instructions allowing you to set up a test environment which should enable you to debug the problem.

Regards

Leo

Yes the requests are for day data. I don’t think the request details make a difference, but fyi for all the requests the no. of days was less than 30.

I have been testing 2.3.0.7 and encounter a similar problem although not symbol related.

If you request historic data from multiple threads (2) via com, for 100 symbols (most times the hang will occur before 50 are processed), IQConnect will hang at some point, never at the same place or symbol. It appears to be a timing issue, IQConnect becomes completely unresponsive with no cpu usage as if it is in a deadlock. In every case both threads continue to work normally after having requested data and waiting for OnDayCompleted.

Reverting back to 2.3.0.1 the same routine runs perfectly. I have not tried any of the versions in between.

Also, when 2.3.0.7 does return historic data, the time between the request and the callback to OnDayCompleted is considerably longer, probably, if the routine did complete, would take at least 4 times longer to process the same series of symbols.

IQFeed Developer Support » Proxy Jun 2, 2004 11:04 AM (Total replies: 1)

How do I configure iqfeed to connect through a proxy?

I thought it was possible though a registry setting, but looking through the documentation again I cannot find anything.

Thanks

Leo
