[molpro-user] Spin-Orbit Coupling in Molpro

Dear Molpro Users,

I am trying to calculate the spin - orbit eigenstates for the Na - Ar 
complex in Molpro 2008.1.  I have run calculations for the Li-Ar complex 
and everything works the way I expect it to.  For Na-Ar with the 
aug-cc-pVTZ basis, the calculations crash once they enter the SEWLS 
program, without printing any error information.  I tried using the 
cc-pVDZ basis set and the calculation does run, so my problem lies 
here.  The calculation is not very large, it only takes about 1 minute 
to do the CI with the bigger basis set, so I'm not sure why it crashes.

Any help would be appreciated.
My input/output file is pasted below:

Thanks,
Jeremy
