For what I suppose is a lightly loaded machine, that is just plain
weird. What's the platform exactly? Is it possible that the
postmaster
is being launched under very restrictive ulimit settings?
If it's a Unix-ish machine, it would be useful to look at "top" and
"vmstat" output to see if the machine is under severe memory
pressure for some reason.
