That's strange. I believe your limit is a little bit behind 50 requests per second. I mean it should be less than 50 not equal to 50. My code has been well tested and I'm using high precision timers in order to throttle the output and using 50 triggers the exception. Received confirmation from others that adjusting it a little below fixed the issue.

I'll let you know once I have more info.
Thanks,
Mathieu


My changes with 2.6.0 works well but you need to limit to 8 concurrent clients. For some reasons, passed this limit, even with the throttler in place, I'm getting ErrorMessage: Too many simultaneous history requests., MessageTrace: E,Too many simultaneous history requests.,

Hope this helps.

Hey Tim, thanks for your reply.
