"%mem=3000MB" in the Gaussian input file). As the result I get:

Check what the OS limits are (ulimit -a or ulimit -m). We get this
error under a PBS queuing system when the user attempts to allocate more
memory than asked for in the job request because the queue system sets
the memory limit. I have noticed that some linux distributions are
setting these limits auto"magic"ally (eg core dump size = 0k).
