Thanks all for the info. I'm going to closet the sysadmin and clobber him
(unset noclobber). Well, I'm not really, it ain't his fault. Trouble is,
this is one of two solaris boxen one of which (the other one) runs an Ingres
DBMS so the tmpfs in RAM is good for that box. We'll have to investigate the
whys of this particular crash (this box has had two spells of uptime in its
~five year life to date so we're not generally low on swap).
