>From the error message it seems that ORCA program crashes. Unfortunately, Orca is no longer supported, which means that if the ORCA's input or anything else has changed, the gromacs interface may fail.
What you could try is to use the version of ORCA that others have used before.

Dear Gromacs Users,
I've been running a QM/MM calculation on a protein with fluorescence probe, using gromacs 4.6.7 (double precision with MPI) and ORCA 4.0.1. The following lines were included in the .mdp file,
QMMM = yes
QMMM-grps = QMatoms
QMmethod = B3LYP
QMbasis = 6-31G*
QMMMscheme = ONIOM
QMcharge = -2
QMmult = 2
The run was aborted with the error messages,
FATAL ERROR ENCOUNTERED
