I was experimenting with (amongst others) a glacier, when I noticed that some rocks behaved strangely. The overall small displacement seems to be stretched or warped, or whatever you call it (encircled). There's almost always some rocks that flatten in a strange way. Does anyone know how to avoid this? You don't always see it until a large render is completed.

I have had this happen. I just call them puddles and throw a disk with a water shader over it. Mine occur on the horizontal parts of the rocks.
This happens when I use a lot of noise in the tweak noise tab.
looks like becoming an excellent render btw, sorry I cant help!
Cool render!
You use fake stones for the rocks I see, did you disable "blend as stone density"?
Yes, I learned well from this forum ;) Perhaps if I throw another fractal over the first (or merge them) it would texture the flat areas as well.
I thought so too, but perhaps you missed it somehow, so therefore I tried.
Disabling the blend as stone density fixes it mostly, but still you can get odd shapes. Perhaps a new seed might help, but it could also make it worse, difficult to say.
I don't know (yet) how useful the displacement tolerance setting in the planet-node is for this. None to very little is explained about this so far.
Perhaps changing it with tiny amounts could help, but it's really a wild uneducated guess.

The only help i've found with the displacement tolerance in the planet node is when parts of the image are not rendering at all or getting cut off like this: http://forums.planetside.co.uk/index.php?topic=5553.msg58325#msg58325
My guess for your problem would be as Martin suggested playing with the seed until you get a mostly clean set of stones.
