SUMMARY: bad patches

Albert White (albert.white@sun.com) hit the nail right on the head.
Sun has a very detailed "System Test and Performance Regression Test
cycle".  He referred me to this site:
 
http://sunsolve.sun.com/pub-cgi/show.pl?target=patches/sys-and-perf-test 
 
Nonetheless a few problems get through or I would not be
writing this in the first place.  BTW, the High IO problem
that got me to posting to sun-managers has been followed up
by Eric Paul below.  In a nutshell, Veritas writes stats
directly into kernel space; Solaris changed a kernel
structure and the space written to has the IO counters.  See
info from his follow up below.

I also experienced this problem (although I didn't realize
it until I read this summary this morning.)  I just got off
the phone with Sun and received the following information:
 
Yes, it is a known bug with 108528-29 and Veritas Foundation
Suite.  (Someone decided to change the format of a data
structure, and add new stats to the MIDDLE instead of the
END, so Veritas writes it's I/O performance data directly to
Kernel-space and now those locations are wrong, so it looks
to the Kernel like there are BILLIONS AND BILLIONS OF WRITES
when in fact there are not.)  Sun assures me this problem is
completely cosmetic and there is no reason to panic.
