Game crashing due to Memory

My computer is crashing due to a memory issue, however, my computer has 32 gb or ram. When i run task manager during wow I see that I am only using 14% of my memory in total during normal loads. I haved tried closing everything but WoW and I still get the crashing error message so I don't think my memory is the actual issue unless my computer is still restricting the amount WoW can use from some type of setting. Moreover the error message says the amount of bytes requested was 10,921,912 bytes (10 Mb) which isn't exactly a lot.

Here is the error message:

"This application has encountered a critical error:

Not enough memory resources are available to process this command

Program: C:\Users\User Name\Documents\Games\World of Warcraft - WotLK\Wow.exe

File: .M2Shared.cpp

Line: 267

Requested 10921912 bytes of memory

Press OK to terminate the application"

Anyone have any ideas what I can do to fix this?. Thanks
