We cannot replicate any crashes, and nobody reported them, surely not in P3D, where available memory is plenty.
The most common cause of crashes in P3D4, are AI airplanes not made for FSX/P3D (usually the ones converted from FS9), and they are easily confused for being a problem of the airport, because not all airports have the same AI schedules, so it's easy to be mislead the cause it's the airport ("it doesn't happen elsewhere!"), when the issue is a particular combination of AI/livery that won't appear elsewhere or might not be very common in other places.
