	Well I employed my database code adjustments yesterday afternoon... and they seemed to have had a decidedly opposite effect than what we expected. So I reverted them back last night. Back to the drawing board on that front - I'll think we'll basically move from understanding the problem to eventually adding more hardware so it isn't a problem. The key to that is getting hardware to work. Eric figured out the issues we were having on one of the newer Intel servers (the RAID controller card had to have a jumper moved around, even though I checked the jumpers already and they matched a similar card in a similar system that is working just fine). Of course, it's a hardware RAID controller, and it won't let me do JBOD, so I was forced to make 8 individual RAID groups, each containing one drive. This is annoying enough, but they RAID bios contains primitive enough mouse drivers that each step of pointing the mouse and clicking on the appropriate button took anywhere from 5 to 60 seconds. So it took me about 90 minutes to configure the RAID. Of course, we could have just stuck with using hardware RAID but for benchmark purposes we're comparing this system to one with similar software RAID. So there ya go. Our BOINC server - one system that handles the boinc.berkeley.edu website, all the alpha project stuff, etc. - has been having more and more problems as of late, all resulting in the CPU load spiralling out of control. We're in the process of getting another one of these new Intel servers up and running to replace this older server. Of course, we're hitting all kinds of other problems trying to boot the thing. More on that tomorrow if it's still offline. Downloading FC11 today. All the mirrors are jammed. And of course we had our weekly outage. No big developments there - Bob took care of all that. He did notice during our weekly science database backup that we had some corrupt database pages. This may be because of something else he discovered - the disk space made available for Astropulse had filled up sooner than expected. So he added more disk space to those tables. - Matt ____________ -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

All right, so I can stop bugging David about it when we're getting all those page time-outs and the "Fatal error: Call to a member function enum() on a non-object in /home/boincadm/projects/dev/html/inc/forum_db.inc on line 28" again. :-) It wouldn't be that spammer on Trac that's causing all this, would it? Thanks for the update. ____________ Jord - BOINC FAQ Service - BOINC User Wiki Real is just a matter of perception.

	Glad to hear you are bulldozing through it all Matt. The Intel Server / RAID controller interface will get easy after a while but I am wondering why you are using a mouse? I have always used a keyboard to configure those controllers and have never found it overly difficult. Anyways, onwards and upwards. It will all come together soon enough.

	I have been trying to upload a completed task for the last hour. It seems to be stuck. Is this part of the Groaning?

	I remember back in 29 August SETI had major problems due to hardware failure devoted all of us was distressed what would become of a data results. Those days you had to battle it out with ancient equipment, but these mainframe computers you had are awesome to check out, I do recall viewing web pages about them, I would like to see seti to keep a web page area about the history of seti and its migration on computers it use over the years and the specs, us geek guys envy and love reading about this stuff. I recently comeback to seti, I was not able be get back online, no I utilise 3G Broadband internet, before I had no access to phone lines, as soon I was online, one of things I made sure of, restart boinc, how devoted I am to seti, I had to come back using boinc. Technology how much things that have change, LOL Iam sure those aliens would say about their crafts. David ____________
