PTR requesting memory

[Protqt]

Right so starting off saying that it's my virgin thread here - Not sure if I posted it in the right place.
Anyhow, I've been playing on PTR every day since it was official and today when logging in I keep getting a WoW error saying that the PTR is requesting immense ammount of memory from the PC, I've got a new-ish PC for 1700£ which I've never ever had a problem with so far.

Is there anything which might be causing this etc, any help is appreciated.

A quote of the error message would probably be of a lot more use.

Also, does it look like a system error message, wow error message or 3rd party error message?

It's a WoW error, the normal client works fine - It's just the PTR one which crashes.
I'll send the error message to you, might be considered spam here
