General rule of thumb: if you’re seeing an something that looks like an interoperability issue with iOS, please file a bug with as much information about the problem as you can provide.
The Bluetooth team loves fixing issues like this and well-written bugs from our developers help immensely to see what’s happening "on the ground", so to speak.

>> I have seen it a few times. For me it turned out to be bad ACK/ NACK of a packet. Sometimes a packet would not get ACK’d, sometimes an extra ACK was added. I can not remember if both caused the lockup, but at least one of them did. I would even look for cases where you receive a packet, then send a packet, then ACK the received packet. This interleave of send and receive processes may confuse it also.
