Post From: Order modification failed when fast/concurrent sends (IB API)

When modifying an order repetitively, quickly, such as using keyboard shortcuts to tick up/down a limit order, I get the following missed modifications. So clicking 8 times quickly, maybe ends up moving it 4 ticks, since some of them results in the below errors. Doesn't look like there is any limits on the IB API would cause this according to their documentation, but who knows.

Wondering if this is irresolvable and has to do with IB API..

Thanks
