Started crashing again

I am having about 2 crashes a day in last few days the really frustrating thing is the 10 minutes it takes to rebuild the database. There are appears no pattern to the crash and there is no error on system logs. Wouldn’t be a big deal if it didn’t take so long to rebuild. I can’t paste version number coz it is still rebuilding - it is a beta you gave me to fix the slow searches

Still rebuilding … so tedious - at last - Version 4.0.15488.0
