+ IMHO:
Any time craft start the system oscillates at its natural resonant frequency + Gravitational acceleration in every part (alone) with different weight = our "strange destructive vibration" for for the whole design to torn it apart.

+Is the game has the concept of damping of oscillations for each individual part? It seems that separate parts of themselves, do not springy. Thus, there appear to damping from contact with the ground. Nothing softens the resonance. And Gravitational acceleration increase speed (different by mass) of each part then they hitting ground.
Just Make 45 degree (to ground) empty long rocket booster and simple drop it. It not spring at all. And then look how long metal tube spring in real life https://youtu.be/FXAUMW0pk3Q?t=36s =Drops, bounces, and vibrations are damped under the action of gravity. You can take a pencil and drop it = same effect. But in game we dont have it. So if each part does not come into equilibrium, what will balance the entire structure? IMHO In game= Gravitational acceleration +> ground hit +> recoil +> 0 speed +> Gravitational acceleration ++> ground hit ++> recoil ++> 0 speed ++> Gravitational acceleration +++> ground hit +++> recoil +++> 0 speed ...etc... ++++++++> ground hit ++++++++> recoil at speed what torn craft apart and then devastation of craft?

And something for it:

ps^ I don't know how is written "physics" in this game, but I think that was the problem . Maybe I'm wrong totally

Today was looking bugtracker and can be found a similar result of physics bug ... What do you think they are similar? http://bugs.kerbalspaceprogram.com/issues/8095
...because when the time is speeding up - the game is even worse expects physics and hidden bugs crawl out. If the official testers confirm it can make reference bugs at each other?

It's... possible that they could be related...

Would be nice if some other people could give feedback on this though as it's probably a complex problem.

I can confirm that I am having this same issue. It appears to be originating from the docking port between the science lab module and the core of my mun base.

Pics: attached.

Could you share the craft file of that?

Did 1.1 fix this problem?

Yours is, yeah, and the explorer craft are fixed.

Still in 1.1.2. Glad to see this is confirmed and high priority. It has me ragequitting.

What do you need clarification on? Just wondering.

All good smjjames... Trigger pulls out the prepared response

Hi, we are doing a mass cleanup on reported bugs, you can read more about it here: http://forum.kerbalspaceprogram.com/index.php?/topic/143980-time-to-clean-up-the-bug-tracker/

The TL;DR is that its not an indication of anything wrong with your report, there are soo many old bugs in the tracker that we cant give the devs a good picture of whats still an issue - so we have set up a process for all bugs from pre 1.1.3 to collect the info and get them confirmed for the devs.

We are trying to check whats still in 1.1.3 - the newer ones will be treated more carefully, but we are trying to clear anything thats no longer relevant to give the devs a clear run at whats important to the players.

Sounds like this one still is, if its still in 1.1.3 we can set it confirmed and keep this open

@KenSharp: I think what you are seeing with the landing gear though is a separate issue all together. There has long been problems with landing gear such as the ones you used. Wheels and Aircraft landing gear don't seem to exhibit this problem so I always use them now for my space fairing ships and landers. The gear you used, when extended and locked to final position, exert way too much spring tension (as if some additional force just pounced on your craft and they bounced). I've gotten away with using them on Mun at low tension but on Minmus I have to turn them all the way down. Forget using them on lower gravity planets. Might as well land on your engines or other parts then.

A similar issue with regard to landing gear on the runway used to exist where a stationary object would moveabout sideways even with breaks set and no thrust. This only occured with aircraft landing gear as I found a Unity bug with spheroid or torus shaped colliders not sitting still on flat plane colliders. Putting up a box collider around the point of the wheels would have fixed this. I haven't tested that bug lately though.
