Critical error?

I keep getting this error that crashes my wow client "This application has encountered a critical error: Not enough storage is available to process this command. File: .\M2Shared.cpp Line: 267 Requested 1164672 bytes of memory.

Can someone help me with this please?

I am using the Wotlk client on Icecrown.

does this happens when you are in Dalaran? in that case is beacuse of WoD models.
You can remove WoD models by following this guide: http://forum.warmane.com/showthread....the-old-client

It happens on the old client also but when using the new client with models it does happen faster like within 5 minutes of loggin on.
