Wheee!! Sun-managers strikes again.

Within 24 hours, I had Hal Stern (stern@sunne.East.Sun.COM) explaining
the problem and asking me to look at the successor to patch 100330 and
Tony Rick ( who gave me the following
concoction he had administered to his ailing 670 which was exhibiting
the same problems. wrote:

Included was a previous post to sun-managers dated Fri, 12 Feb 93 8:15:34 WST
from Adrian Booth ( who had encountered the same problem
and detailed the fix.

Tony ftp'd the patches over, I installed them, one of our system
killers flailed at it and nothing went into disk wait anymore. It
simply ran out of swap and died like it should have. Yeah!!

Now, our drooling masses of simulation and analysis junkies can descend on
our server.... Oh No! What have I done???
