Dear Molpro developer,
                                How to rectify the error in single point
calculation of ccsd(T).
The error have been pasted below

Molecular orbitals read from record     2100.2  Type=RHF/CANONICAL (state
1.1)

 ?Error: RHF not converged. This error exit can be avoided using the
IGNORE_ERROR option on the ORBITAL directive
