It is OS-dependent.  Some versions of Linux have a very nasty habit of
killing random processes when memory gets scarce.  I'm not sure what Solaris
does.  And it might even be code in Sendmail's libmilter which terminates
when memory is tight, so it's extremely difficult to control what happens.

I do not know why it isn't dumping core.  Solaris experts?
