Hi:
as I add more symbols to my monitoring with real-time mkt data subscription, I start noticing that there's a queue buildup of tickPrice messages (and perhaps all other as well).
It shows itself as a delay in refreshing quotes in my application. When I stop my application, I can see a final "avalanche" of queued messages in the console output.
I guess I have a race condition somewhere in the code, I am going to look into it.
Meanwhile, do you know any way to monitor the ibapi incoming queue, so that I can detect a buildup and delay early?
