Further information
The job starts with the first five steps and then stalls and eventually gives a segmentation fault.
..Perhaps my desktop is insufficient for a HFCALC...

You should keep in mind that hybrid calculations take > 100 times the DFT time ... So you might need more patience ...

A good start to check whether or not it works at all. You might also look with the UNIX command top if your memory is sufficient or if the OS starts to swap.
