Can OnTick() miss incoming ticks?

Is it possible that OnTick() handler in cBot misses some incoming tick if OnTick() still executes when the tick arrives? 

Our platform puts all incoming ticks to the queue. When we handle items from the queue we apply all collected ticks to MarketSeries, but invoke OnTick handler only for last tick. Therefore, OnTick handles only latest known ticks.

Also I have seen a situation that when viewing two identical 1-tick charts in two separate instances of cTrader, a tick was missing in one instance and present in another.

Tick chart shows all received ticks. Do you compare two instances of cTrader from the same broker?

Are there are kind of throttling in cServer when it sends (or does not send) ticks?

No, there is no throttling in cServer.

Yes, cTrader was from the same broker and both instances were usung the same account. But that was observed around half a year ago. Unfortunately, I do not have a screenshot.
