Getting error when trying to log chars in Dalaran

Yello, like the title implies, I keep getting error when trying to log characters who are in Dalaran, I have no trouble logging characters who are in Ironforge...I've deleted cache folder, used character unstuck option on one of my chars, nothing worked. Any suggestions or explanations as to how to fix this / why it's happening?

It's probably because of the amount of active players in Dalaran causing your client to crash. There is an application, if I recall correctly, named Large Address Aware that allows your wow client to use more than 2gb of ram at a time to stop it from crashing due to running out of memory.
