I signed up for a test account to try running 3 on one computer over the weekend and ran into this issue. I can run 2 instances at 1680x1050 with max settings and get ~50fps on both. Opening the third instance did what you describe, random disconnects. I tried running the second and third instance minimized at minimum settings and 800x600 resolution but still ran into the same problem.

Running a Core2Duo (assuming that's why I can do 2 instances of WoW flawlessly) with a GF7800GT and 2g dual-channel ram.

Never got it resolved, so I gave up on trying to do more than 2-boxing for now .
