I can't see the error you mentioned with MPI-2 Molpro2010.1 PL20 so far.
I tried your input without any modification first, and it failed
immediately because you have not set memory in input (the default is
only 8MWord). I have added
in input, it appears to work fine so far (still running). Could you
please try the new input on your side?
