I recently got a new computer with 8gb of RAM, and since then World Of Warcraft crashed very often with out of memory errors.
After banging my head for hours every time I crashed in dalaran or coming out of the arenas, I finally discovered setarch(8).

While it isn’t a perfect solution, it work’s for the most part.
