That would have been a very important piece of information to start with. We already know that MDX doesn't work well in 7.x.
You're right, I had hoped the debugging information would be enough for Khaled to locate the problem
Unfortunately, MDX is not the problem.
Now disabled DCX as well. Have to run it for a couple of days before I know if it doesn't crash anymore.
6.35 doesn't have this problem.
