First check what the hell is actually going on with this map. Use Unwrap UVW and Edit map to see how does it behave. I suppose that in mudbox everything looks fine.

It looks like your UVs have some mirrored portions, i.e. the normals are facing in the opposite directions. Mudbox can not handle such UVs properly.
At least I had similar issues when some of my UV elements were mirrored.

I hadn't have such problems but I've had some few days ago. I've made texture and bump layers. Texture worked fine in max but bump didn't. My character has empty area in the center of his back and some mess where legs are connecting with body part. Problem is solved but it's strange that there are two maps made in one file and aren't working both same way when use same UV. Freaky and it was pain in my ass for a while.
