Oops, not good..
Unfortunately, the dump you posted is not enough for me to give you any advice. We may try to simulate the problem, but I personally doubt that we will succeed....
Anyway, are you positive that it is connected to the memory scan? Is it always the case that if you skip the scan, everything is OK, and if you let it finish it crashes??
Tell us more about your computer - brand, OS, RAM size, etc... - anything you can think of... Thanks.
And besides these crashes - everything is working as expected? The resident protection is OK?
Sorry for this,
