Once you've got a ulimit in place so that malloc eventually fails with
ENOMEM, the backend process should print a memory context dump on stderr
when it hits that. Make sure your logging setup captures the process
stderr someplace (logging_collector works for this, syslog does not).
Post the dump here when you've got it.
