Yep, responsible for serving about 80 million requests per day
Me, too. I've been using it for development systems, QA environments, and some production services. The instabilities have been due to ongoing software development, now that the "install a modified glibc" requirements seem to have vanished with the tweaks of the latest kernels under RHEL and CentOS.

If so what is maintenance like?  Are you constantl
having to keep a careful watch?  Does it crash
often?  Run out of memory? OR is has it been
a very blissful experience and your always confident
that it's up and running.

I've been quite impressed -- it's never really been a hassle.  Nagios keeps
an eye on things, and we're running heartbeat on redundant machines to make
sure that even if something goes pop we're still covered.  Even with all
that, I can't think of a production failure (even non-customer-impacting)
that has definitely been Xen's fault.
What are you using to configure your Nagios? I've been working with fruity, that seems to be a nice tool but need completion.
