[AMBER] about error with "Must have more residues than processors!"

Hi, all.

I plan to run my CpHMD job on 208 processors at 26 nodes, but it's stopped
with Error "Must have more residues than processors!"
Now I redo the job on 80 processors and no problem.

Could anyone explain the reason of the error?
Weather the number of processors cannot more than the numbers of system's
residues?

A part of mdout:(I also attach the mdout and log file to make more
information)
