What do you mean by 'stop'? Does it stop and crash with an error message?
Does it just stop producing output and hang forever? How many CPUs did
you try using? Did you try using fewer? Are you using just 1 node?
Multiple nodes? If you were using multiple nodes, does it start working
if you reduce the number of processors to only use 1 node?
We need as much information as possible to help.
All the best,
Jason
