Dedicated server repeating CTD without any apparent reason.

[Amarok_73]

Hello,

Is there anybody that can tell, what may be the reason of such CTDs on dedicated server? Looking into the log file, I can't see in the crash description itself, anything that would lead to any specific reason, only the multiple repeating messages about IL-76 hit by Mig-31 and vice versa preceding the crash message itself makes it look quite suspicious.

Supposedly there is a problem with Tanker AI causing a fault when it uses an algorithm to find a base to RTB. It seems a plane has crashed into a tanker the instant before your crash. A workaround for this might be to ensure tankers have a valid place to land nearby that is not destroyed by craters n stuff.

I've not tested this, just heard about it.

@FusRoPotato Unfortunately there's no track I could review to check this theory, but it sounds reasonable.

Maybe this can happen if there's absolutely no available base for the tanker (because it's too big or because all bases are neutral or opfor).

Well, this tanker departs from the Cairo East base, which seems to be big enough for him, and is of the same coalition as the plane, so this isn't the factor. Besides, this time the server was about the one hour plus awake then crashed, but this mission sometimes can last for like 6-16 hours without any disturbances.
I've disabled for the AI planes the possibility to refuel from the tanker, and I'll see what will be the effect.
On side note, have anybody else noticed, that planes in the queue to the tanker are overlapping each other without colliding? I wonder if that is supposed to be that way...
