Seems to be randomly happening different machines and different drawings.

How do you keep it from giving you this error in the first place
If I knew the answer to that I wouldn't be sitting here...
Sorry, couldn't resist

Seriously, internal errors in AutoCAD can be caused by most anything and are
very difficult, if not impossible to track down. "eLockViolation" can mean
that an object was locked and an application is trying to write to that
entity. I have never seen "eHandler use".
Does this happen at random on any drawing, or just in a certain drawing? Can
you provide a set of steps to cause this error to occur?
