bump still an issue. vac works on all other games and vons but not for arma 3

I thought my friends werew all crazy when they said they keep crashing. I wasnt having any issue. I was even streaming on twitch. Then all of a sudden 10-of the 15 in our grp all crashed at the same time. I didnt. Then about 2.5 hours into gaming boom game locks up and had to do a hard reboot. after that every 30 mins or so it would lock up again.
