Well, I guess I should post here just to say "no news is good news". All my "children" are up and running happily. There's a little less adventure now that I've learned quite a bit about Solaris and my SPARC/Ultra boxen. That doesn't mean that challenges don't still exist.
I did wrestle a bit with the UPS I bought some time ago. Turns out that while it's supposed to tell me when it's overloaded, it doesn't. Well, it does tell me, but it does it by shutting down and therefore causing all the boys to reboot about once a week, with the smallest power hiccup (my other machines, not on UPS, would soldier right thru these hiccups) . Ironic that using a UPS has caused more reboots than not having one, eh? So, I finally broke down and moved sparky and buzz off of the UPS. Now it's just zap on there, humming away.
I continue to run SETI@Home on both buzz and sparky. I'm getting up there in rankings. Seems that it's pretty easy to hit the 75th percentile, but beyond that it's hard to make progress in the rankings. I suppose it's because of a hard-core group of folks that have been running SETI@Home for years on bunches of machines, while most people have run it once or twice, then lost interest. With the processor speeds of sparky and buzz, it will take me years to get near the top.
