this usually happens when the game runs out of its set memory range.
The memory range here is not referring to the limit of windows or system memory. rather it is a range around 3-4GB. I noticed this happens a lot when certain weapon/ground unit use ultra high resolution texture.
I used the exclusion method to pin down and discovered this to be the root cause. It is proven that when I reduce the resolution of the texture thus reduce the memory of those weapons, the crash is gone.
So, when you see the crash happens intermittently, it is highly possible this is the cause. SF2 loads random ground unit and aircraft weapons for AI jets. When the program loads the weapon that has a memory requirement that exceed the allowed memory, this happens.
The simple way is to examine the resolution of your weapons and ground object folder and resize those excessive resolution textures.
It is completely unnecessary to use 4096x4096 texture on a bomb. 512 x512 is enough.
