Arelog doesn't help because it doest work properly, more details in the thread "Arelog" ... so still no solution to this problem.
I have the same issue, but i do pvp and wow crushes in about 3-4 hours. I dont believe, it's wow client, because when i play by myself, it doest crush. And when i am isung HB, run it in the morning and come back home in the evening, i ALWAYS see this WoW-crushing.
I am wondering so much, why developers cant do a good-working relogger, because it's the most needed function and because of this you cant bot for more then 3-5 hours (as for me)
