Hello gurus,

Again, thanks for all the respond to this problem. The problem was that
SunOs 4.1.3 or earlier doesn't ping host with multiple IP addresses -
caused a core dump. Most of you recommend to install patch 100891 from
sunsolve. This will fix the some of the library in /usr/lib and
/usr/5lib. I have downloaded this package. Meantime, there are alot of
activities in this mailhost so I don't want to stop it at this point. I
will install this patch soon.

Thanx to the following:
Matthew Stier
James Coby
Jon Bidinger
Lee A. Fedor
Cheryl L. Southard
Chris Marble
Mattias Zhabinskiy
