The primary MX for porcupine.org runs on a "non-virtual" machine
with 256MB and never has resource problems. It runs, however, with
default_process_limit=30, and there are no other resource-hungry
processes.

When systems lie about errors, use strace and see what system
calls are failing.
# strace -f -o outputfile /usr/libexec/postfix/master -d
Be prepared for massive amounts of output once you get past the
point that things break immediately.
