Many thanks to all who responded, and so quickly, too!
The unanimous answer was that Solaris 2.5.1 is very stable. Several
respondents are using 670MPs with 2.5.1 and find it rock-solid. Some
have suggested that 2.5.1 is in fact faster than 2.3. This is what I
was expecting to hear, but I'm glad to have real feedback about it. Now
I can go back to the vendor and ask what's wrong with THEIR software. :)
A few notes:
Ronald Loftin pointed out that 2.5.1 is the last version of Solaris to
support this architecture. I had read that when 2.6 came out, and it is
definitely something to keep in mind.
Some people provided some cost estimates on moving to an Ultra 5 or a SS
20 platform. Thanks!
