For Solaris: Never. (Unless there's some application software that's
always running and leaking memory.)

At my last job, we had an old Sparc 20 that had been running
continuously for four years before we shut it down and replaced it with
an Ultra 10. I mean literally continuously -- the "uptime" command said
something like 1481 days. The Cisco router on the same subnet had been
running continuously for even longer.

'Course, that Sparc 20 wasn't running Solaris 9, obviously. It was
Solaris 2.5.1. I presume that Solaris 9 is just as stable as 2.5.1
is/was.
