[orca-list] Error in CASSCF calculation

["Martin Straßmann" <mstrass uni-bonn de>]

Dear Orca-users,

I?m trying  to perform a CASSCF calculation with Orca 
2.8.0 (also tried Orca 2.7.0), but it always ended up with 
following error:

CAS-SCF ITERATIONS
------------------
The convergence criteria have NOT been met; however the 
solution may be close enough
  ... we will continue anyways
Canonicalizing the Orbitals    ...
An error has occured in the CASSCF module
CALLING COMMAND: /usr/local/ORCA/orca_casscf 
Orca_CASSCF.casinp.tmp
RETURN CODE    : 11
ABORTING THE RUN

In order to avoid mistakes from the input and to see if 
the system works probably I tried to calculate the CEPA2 
calculation for the Benzene-example from the manual 
(6.1.7.3 on page 97) but it came back with the same error. 
Has anyone an idea what is going wrong? Thanks in advance!
