The message describes the mistake you made. You are optimizing positions
with MSR1a, and your RMTs are too large. When they touch, if the distances
are too large then MSR1a will crash. You need to reduce the RMTs, for
instance use 1.9 for Mo and 1.6 for O.
Note: there may be other contributing factors, e.g. functional, lattice
parameter wrong....
