with an intel i7). coresize is unlimited:

> You might want to make sure that the underlying launcher actually sets the coredumpsize to unlimited on each server where you're running. E.g., if you're using rsh/ssh, check that your shell startup files set coredumpsize to unlimited for non-interactive logins. Or, if you're using (for example) Torque, check to ensure that jobs launched under Torque don't have their coredumpsize automatically reset to 0, etc.
