[molpro-user] Error in UMP2/OPTG

[Pawel Wielgus]

Dear Molpro Users,

what is the meaning of the following error?

ERROR IN POSINP: CODE ^@^@^@^@^@^@^@^@000
NOT FOUND

I get it all the time when using OPTG after UMP2, like here:

hf
wf,40,1,0
occ,8,4,6,2
orbital,2100.2
maxit,100

uhf
wf,43,1,3
occ,  11,4,6,2  !SUM=23
closed,8,4,6,2  !SUM=20
start,2100.2
orbital,2201.2
maxit,100
d(1)="UHF-4A1-A1-A1-A1"
e(1)=energy

ump2
orbital,2201.2
optg
print,history

Both hf and uhf pass correctly, and the error occurs after the first opt
step for ump2.

Any ideas will be kindly appreciated!

Regards
