	Over the past few days (starting around Friday) we had continuing fallout with the science database repairs made over the previous weeks. Nothing we couldn't diagnose quickly or handle, but there were patches of low workunit availability. Long story short, after rebuilding our workunit table we hit some index corruption issues that didn't rear their head until we suddenly stumbled upon them. Today we dropped all the indexes and rebuilt them from scratch during the usual weekly outage. So far so good. I also used the outage this week to upgrade the OS on the scheduling server (which was fairly out of date). We also brought in some freshly compiled splitters which contain new database plumbing - a step toward us having the splitters themselves being more sensitive to telescope status when the data were recorded. This code is currently dormant but after some testing and calibration will ultimately keep us from creating and sending out large numbers of "noisy" workunits. This plumbing however hasn't been compiled yet into the Astropulse splitters, which is why they shall remain off for now. - Matt ____________ -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

	Thank you for the update Matt. I can hardly wait for the new servers to arrive, and be of some help. I remember well the anticipation of when oscar and carolyn arrived. Steve ____________ Warning, addicted to SETI crunching! Crunching as a member of GPU Users Group. GPUUG Website

Steve Yes, thank you Matt so much for the info once again, it is always of much interest to us what goes on each week. Helps some with a little less patience understand the things you have to deal with just to keep the project running.

It's not the end of the world... Thanks for the update, Matt. No problems whatsoever. I managed during the days when AP's where easy to get, to accumulate so many AP's, that I can stand an AP drought lasting for 2 weeks or more. I do not need to allow any MB's into my AP only machine, and I do not need to run any MB's on the CPU's of my Nvidia computers either. I will just relax, and wait patiently for whenever they turn on the AP splitters again. Burp.....:-) ____________ /The grumpy old Swede.

	Ah yes - I just set the "show_results" flag back to 1. Thanks for that. It helped me to abort this unnecessary AP WU, which was already validated. Makes 26-28 hours of CPU time, which can now be used for something more useful. ____________ .

	Hi Matt, Great news, I hope however this doesnt mean you have to work 24/7 to get them in and working.. Seems to me you've been pretty busy as it is. Dont want you going down with exhaustion.. The resultant outage would probably take ages to sort out. Regards, ____________ Cliff, Been there, Done that, Still no damm T shirt!
