Ghost console fails at 99% with could not allocate page table memory error

I've been using Ghost Console 11.5 to take images of laptops prior to redeploying them, it's been working fine but recently on a number of different models the client will install OK and I can create an image create task and run that OK and it all appears to be working OK and will then get stuck at 99% complete. If you look at the laptop i'm taking the image from it's no longer displaying the ghost image create screen and sown multiple instances of an error saying could not allocate page table memory.

Anyone have any ideas, bit stuck as to what woudl be the cause. Given that teh image process starts OK I doubt it's network drivers.
