Our CUPS servers are running in Linux systems. Our clients are all AIX
and Solaris multi-processors and huge-gig of RAMS. We have true 2700+
printer queues shared between these clients. At CUPS 1.2, these clients runs cupsd very happily.

CUPS 1.3 brings new features, major and minor patches for performance,
security, and etc. But it also brings with it not seen in 1.2, at least
from what I've seen so far, issues that I've yet to convinced myself
that it's just my systems and not CUPS. BUT, how could I be confident to
say that it's my systems that are the issues if they run 1.2 just fine?

Anyway, I've yet to test CUPS 1.3.6 in Solaris. But I'm almost certain
the issues I saw in 1.3.5 will still be there...much like the ones in
AIX.

Hey, if there were no problems....I'd be out of a job, with or w/o CUPS!
