 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).
