Dear Zhihong,
Look in your qmBaseDir, where ORCA is writing intermediate files.
In your case, It is /dev/shm/NAMD_Example1
You should see a .TmpOut file which is written by ORCA for the current QM/MM step.
Since it is an ORCA specific error the TmpOut file may provide more details about the error.
One thing I did notice in your conf file that may raise some problem.
You specified to have 10 QM calculations while passing charge/multiplication information for only one qm region.
qmMult "1 2"
qmCharge "1 -1"
I assumed you have 10 qm regions since you requested:
# Number of simultaneous QM simulations per node
QMSimsPerNode 10
Best,
Atanu

Deal Namd,
I came across a issue when I run a QM/MM simulation，
TCL: Minimizing for 100 steps
Info: List of ranks running QM simulations: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
[file orca_tools/Tool-GTO-Bases/basissets.cpp, line 706]: Wrong number of basis-sets stored!
FATAL ERROR: Error reading QM forces file.
------------- Processor 0 Exiting: Called CmiAbort ------------
Reason: FATAL ERROR: Error reading QM forces file.
I do not find the solution in the mailing list and ask for help, any suggestion will be much appreciate.
My Namd config file as follows:
