Nobody can tell you anything without exact system info or other technical details. Typically this happens when the program simply runs out of memory. You can always try to pre-convert your Raws to TIFFS or whatever and this may avoid some overhead associated with invoking Camera Raw and allow you to get your panorama.

mylenium said ture nobody can tell you anything without exact system. I'm say something to you. Have you empty space in your computer?

That is such a leading question, and I suspect I am not alone in thinking of a suitable response, but I don't want to get into trouble.

That result seems to indicate not enough overlap or reference features.

Is your system performance an issue?  You can set ACR to output something less than full res files to ease the load.   Keep an eye on your scratch file creation while the merge is being processed.  Are you running out of scratch space?   What are you system specs, and how much memory have you allocated to Photoshop?  Have you left the OS enough to manage all the file handling as well as its general house keeping?
