The exceeding 17000 queue will trigger 2002 is crazy.
so when it's more than 17000 people it's going to kick everyone out of queue and hope for the best. And most the cases people will re-queue again with anger.
I mean long queue time is expected, but kicking you out after few hours of queue time and start all over again is really messed up.

What is the point of putting yourself in the queue when it's going to be shuffled again as soon as the queue reaches 17000 people?

And the problem isn't "there is too many people queuing now", is "the queue system design is kicking out people within 17000 queue priority".
