I would suggest that if the pipe is turning then you _may_ be
overtightening the fitting.
My most recent exploits with comp. fittings were sorted by the
application of a plumbers silicone sealer (Fernox LSX) around the olive
prior to assembly. It's holding out so far.

I am not overtightening. I am just tightening one turn after hand tightening.
I don't use any sealant or jointing compounds with compression fittings. According to the recommendations by the manufacturers, they are not needed and can, in the long term, jeopardize the fitting.
A clean olive and pipe does produce a joint without leaks, in my experience (save the turning pipe issue above)
