The topic speak for itself.
The process is taking like 0.18 % CPU time while no memory commit nor private change for longer than 9 hours (while I was asleep).
I'm going to downgrade version update 3 disregardiging update 4 which is actually 3, and wish me luck!
I'd like to post ling to like 20 GiB dump, but the ProcessExplorer is tooking to much time to debug (I waited for an hour to make a dump).
