Constraints don’t constrain anymore!

I have a largish assembly, 400 or so individual components, (Some individually quitedetailed, such as gears.)in nested assemblies. Lately I'm finding that the assembly constraints aren't constraining anymore: I'll have a sub-assembly whose position in the overall assembly is fully constrained, and yet it can be freely translated, and can't be made to snap to the position the constraints specify.


In messing with it, I found that the coincident mating and aligned constraints were acting as though they were still offset by the amount they defaulted to when I imported them. If I switched them back to offset, and set the offset to zero, they moved where they were supposed to be.


That got me part of the way there, but it's not helping with the constraints that don't have offsets, like aligned axis. Of which there are quite a lot in this assembly. Any idea what might be going on? Perhaps the assembly is just too large for my workstation's memory?


I am getting a "Failure to assembly based on current connection defintion" error when the assembly is updated, but I can't seem to locate the problematic connection.


I'm running WF3.
