This could be my problem too. But it has happened everytime I have submitted the batch job, but after several hours of running. If I try with a simplified geometry then the job completes properly and quickly.

That is why I wanted to know if there is a possiblity to run for only a few events (few collisions in my case), so that the job (with the full CMS geometry) has a chance to finish soon.

.... bus errors are usually problems connected with the operating
system/hardware of the computer you are running on and normally they have
nothing to do with Fluka. On our cluster we get similar errors (very rare)
if the node the batch job is running on temporarily loses the nfs
connection to the master node, but I do not know if this applies to your
case as well
