My system has 8 GB ram. "Plenty" for all other apps and for the way I use my PC, never had "not enough ram" trouble nor 'feeling'.
CPU usage (when "CORE update definitions" is running for ages) is around 30% (25-50%, loads of other apps running in background), ram usage around 4-5 GB.
Process Explorer says SAS is using 25% CPU when (not realy?) processing the Core definitions update.
I never had this problem with SAS , only lately (couple of weeks now, so I guess the problem came with the latest program update).
I just noticed the CORE-update is busy (is it?) for over een hour again, that's why I had a look at this forum, to see if some solution has popped up yet. Seems not...
And "the problem" doesn't accour everytyme the definitions are updated... It's a "sometimes".
And as I mentioned before: uninstall.re-install doesn't fix the problem. Only keeps the customer busy for a while .
