WoW crashing (Lord)

So up until recently I haven't experienced any real issues with the WoTLK client and now for some reason when ever I'm running around Dalaran or even flying out of Dalaran I get these client crashes. Any other time I'm fine, any ideas on what's causing this and is there something I could do to fix it?

Error Message: Not enough storage is available to process this command.

common problem, the workaround is a software posted on this forum which allow your WoW.exe to use more RAM, this will solve your problem.
try to look for it on this forum with search feature

I think this error #134? Check out this link, it provides a possible fix.
