After playing in arma (editor and ingame) for +-7 hours my arma started dropping in FPS (around 20-30) while server was still at 50FPS (not at once but slowly dropping)
After some time my game stated to give white textures for object for a few sec. And then go back to normal.
Then at some random moment the game crashed.

I reopened the game and join the same server. My game had +60FPT after restarting the game. (without changing settings)

Last errors are (in .rpt file)
