maximum and minimum constraints in flexible assemblies (inv 2011)

[Catafratto]

First of all, hello to everyone!

I am making a car where a door is kept open by a pair of gas springs. I made a gas spring axieme, stelo+camicia, and I bound them perno-foro setting a maximum/minimum for the race, and everything works well. I put the springs on the door, I give the flexible assemblies, I move the door and everything is fine. After a while, however, I see the "red cross" of error, although everything continues to work smoothly; still active the design doctor, I confirm everything without changing anything, the error (which is generated by the pin/hole bond on the gas spring) disappears to return after a while. nothing serious, but I'm curious to know if it's a problem others have had and maybe solved.

Thank you.

that of the constraints that after a while go wrong does it to me and not only with 2011.
The error is obviously apparent, because it is enough to confirm them with design doctor, and it is corrected.. .
I've never understood why.
