After upgrading to WL Build 45, I'm getting this IQFeed thread conflict error when accessing a stock for the first time. This error occurs with a plain Chart as well as a strategy. I'm running IQFeed 16 and IQFeed client 6.1.0.20. The Chart appears to be normal. This was not a problem with WL Build 44.

To gather info to attempt to reproduce..
1. Are you using IQFeed build 16?
If so..
2. Did you enable parallel updates in the IQFeed settings?
3. Are you requesting futures symbols?

You can't reproduce this? Strange. Why was this error never showing up in WL7 build 44? Why did Build 45 break it? Maybe this is a WL7 problem rather than an IQFeed provider problem.
As I said in the original post, I'm using IQFeed Build 16 and the older IQFeed client 6.1.0.20. If I upgrade to the new IQFeed client, will that adversely affect WL6? I need WL6 to work with IQFeed.
No. Would it help if I did? I guess I could try that.
I don't do futures. I only do stocks and ETFs over IQFeed. I don't have an IQFeed subscription for mutual funds. Those are done with Yahoo instead.
UPDATE: This problem appears to be with On-Demand updates only. Once a given stock is updated, it won't occur again with that particular stock. It may be a WL7 B45 problem and not a IQFeed provider problem. Try reproducing the problem with On-Demand updates, and avoid all static updates. Are you suggesting the On-Demand code isn't thread safe? Perhaps the On-Demand base class isn't thread safe.

See the build notes about parallel updates to see if you want to enable them or not.
We've got a handle on this innocuous error message. Should be fixed for Build 46.
