We never did claim to have totally solved the "slow feeder query" problem plaguing us a month ago (and well before that). The adjustments we made to the database and the way we set up our queries have helped, but last night and well into today mysql fell back into its old habits again. We have a policy to not care about this anymore as we don't have the time, the problem is relatively transient, and we'll be upgrading mysql versions soon enough. My gut tells me this is caused by some kind of mysql housecleaning that gets tickled every so often depending on load. Aside from that we went ahead with our changes to the science database and employed new solaris versions of the assimilators and splitters. Later (i.e. tomorrow or beyond) we'll install linux versions of the assimilators and validators (thus getting the last remaining backend bits off of kryten). One thing at a time, folks. The validator queue was growing again. Seems like kryten perhaps needed a reboot to clear its network pipes so I did that. Now the queue is draining. Damn pesky mounts! Soon the validators will run on bruno, i.e. the same machine with the result files. That'll be much better. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea. What is hard is to do it." - Jeanne-Claude ID: 537991 ·  |

I don't recall in recent years such a flow of good news: new servers, more donations, astropulse released in Beta (the Windows version has just been released), processes getting more efficient... Good work guys! Bruno is certainly a welcome addition, but no server can replace all your hard work. Thanks! Regards, Wander ID: 538023 · |

I have to agree with Wander, this is great. Its nice to see this project getting the attention and needed donations that are desperately needed. Each and every person who has done any kind of hardware/money donation, thank you. To the rest of those that crunch, thanks for putting up with the problems that UCB has had. It sounds like soon things will be a whole lot more reliable than they ever have been for the project, and that is something that each and every one of us should be very proud about helping with. To the project folks, thank you for the hard work and long hours you all have put in to keep things running. We are all very thankful, more than you all will ever know. Long live SETI@Home, and happy crunching to all. Jeremy

To add to Fuzzy's Note, I received an email that was sent to the poeple that donated roughly over $6000.00 of hardware to make the hardware "fixes" possible. Bruno is not new with exception of the CPU's, RAM and Drives... Making things "fit" took weeks and getting it settled in is taking weeks... In NO Way should any of us start thinking we are out of the woods yet... The path that we are walking has a large clearing that we are going through... Donations are Still Important!

Matt, It appears the upload/download process may have a problem. I have three computers that process SETI on two separate ISPs. One uses cable/modem and two use telephone modems. They do not have any hard coded addresses, either. While they have been able to upload completed work units, none have been able to download new work units or update their stats for over six hours now. Recycling Boinc and SETI and rebooting have not helped, either. This leads me to believe there is a good chance the problem is not on my end. I hate to start your day this way. Good luck!

Same symptoms here on dialup. I tried ipconfig /flushdns and bonic -> Advanced -> retry communcations didn't help at 10:56 EDT project communication failed at 11:00:33 EDT Downloads started at 11:00:48 EDT ID: 538327 · |

Same problem here, all machines, for a couple of hours. Cycled the router, flushed the caches, no joy. BUT, Matt shouldn't waste his time looking at the SETI servers. I'm getting the same thing at Rosetta, starting at the same time. So the problem must lie elsewhere. ID: 538333 · |

Matt, I'm glad that I'm not the only one with that problem. First thought was that my provider was acting up again :( -=[ Not all who wander are lost ]=- ID: 538338 · |

I had this problem earlier today on 5 machines. Rebooted them all and no more problems. They have all uploaded, downloaded and reported. But maybe I just got lucky. ID: 538349 · |

Matt, I had two WU's stuck in download, one from here and one from Seti Beta (they come from the same server), and since I couldn't see any others report about problems with downloading, I assumed it was my host. But they seemed stuck so I aborted the transfer of both, and soon after I successfully downloaded a Seti Beta WU. And now I have an Astropulse WU in my cache. So some WU's seem stuck and only aborting the transfer of them can help the problem to go away. "I'm trying to maintain a shred of dignity in this world." - Me

WTF?? I've got 3 machines running at two different lacations. They have not been able to upload, or download anything for the past 8 hours or so, despite plenty of work being available. Oh, looks like the problem has cured itself as I was writting the above. All of a sudden both machines at my current location "miraculosly" fixed themeslves... Hmmm, looks fishy.... ID: 538362 · |

I've also been having this problem, I've done ipconfig /release /renew and /flushdns, I've repaired the connection and one time the server was offline and then for one time It worked, then It was back to what It was before, SNAFUed. And I have 4 PCs, 2-Intel QX6700 cpus and 3-AMD Opteron cpus, It's very frustating and depressing. http://setiathome.berkeley.edu/forum_thread.php?id=38562 The T1 Trust, PRR T1 Class 4-4-4-4 #5550, 1 of America's First HST's

All my machines are back up, SETI-crunching happily. I hope that means whatever was broken is now fixed and everyone else's clients will get new work soon. The SETI crew can brag that they beat Rosetta today. R@H is still wedged tight. ID: 538386 · |

Ooops, So Rosetta is still borked, Oh well, That just proves the guys here can get things fixed pretty quickly as they are a pretty talented bunch of bananas. ;) Seti couldn't get along with less.

WTF?? I've got 3 machines running at two different lacations. They have not been able to upload, or download anything for the past 8 hours or so, despite plenty of work being available. Generally speaking, the best way to "fix" problems is to just wait them out. BOINC is designed for less than 99.999% reliability at the project/server end, because five-nines reliability would put volunteer/public computing out of reach of most projects. SETI is probably running somewhere between 90% and 99% reliable right now, and when there is a problem overnight, it gets fixed when Matt, Jeff, Bob, etc. come to work. ... and the client software says "woo hoo!" and sends whatever they've been holding for the last few hours. If you read the fora (particularly technical news) you'll see that Kryten is getting really tired, and Kryten's load is being moved to another server. Expect to see things get better as the changes get done.. ID: 538702 · |
