My mac is running stock but i have never had an AP WU on this machine, My old P4 XP gets lots of AP WU I had one of the new AP v5 last week took 8 days to crunch with the stock opt. have one now in the waiting to run that says 175 hours, Aslong as the new AP running stock stays stable i can live with it, but im considering just letting the mac run seti and my old pc running milkyway full time.

I messaged Eric to see if he could kick the Upload server remotely from home From the looks of things uploads are still happening occasionally, it's just all the download traffic clogging the pipe at the moment. Once the downloads taper off, the uploads will be able to get through. Grant Darwin NT |

I messaged Eric to see if he could kick the Upload server remotely from home Pete, It's not the upload server he needs to kick. The communications channel has been saturated with downloads for 20 solid hours now. Sometimes this is because of MB 'shorties' (VHAR), but I've seen no sign of that in my own downloads. Instead, I've been getting a larger allocation than recently of AP_v5, and the ones I'm crunching seem to be running at normal speed. But the server status page is showing AP results being returned at well over 3,000 per hour, yet the number awaiting validation - with the validator disabled - is rising at only 40 per hour. The average turnround time for AP tasks will soon fall below 10 hours, which is ludicrous. I suspect that a significant number of hosts are trashing every AP task they receive, and coming back for more. If every AP task returned is replaced by one new download, then 3,000 tasks per hour - almost 1 every second - requires 8 megabytes of download every second, or 64 megabits of pure data. Add check bits, routing data, communications protocol overhead and so on and the 95 Mbs effective throughput is easily reached. In order to protect the servers from overload, and preserve the integrity of the science database, Eric should be putting a temporary stop to AP downloads, until the cause of the anomaly can be investigated and corrected. Once the runaway download train is brought under control, uploads will look after themselves. |

I cannot download new WU's because my completed WUs don't upload thus it doesn't request more work. One of the safeties built in is a limit on 2*ncpus uploads before work fetch is halted to that project. BOINC WIKI |

Trying to do what little bit I can to help. I've suspended my network activity for the night at the very least. I will try again in the morning and if it's no better I'll suspend it again. PROUD MEMBER OF Team Starfire World BOINC |

I cannot download new WU's because my completed WUs don't upload thus it doesn't request more work. well, this one is affecting me badly as it is affecting other projects also. My 8 core system refuse to get new work from ANY PROJECT! this is not affecting my quad or dual core systems though. so, basically right now I have 16 cores idle doing nothing because BOINC will not get work from any project I attach to. |

The net load is at MAX for the past few hours... Too many WU upload connections or an attack? What if Fiction was Fact and Fact was Fiction and vice versa? |

I cannot download new WU's because my completed WUs don't upload thus it doesn't request more work. I would suggest this is a problem with your 8 core system, as the others are working ok. Problems with SETI@home should not affect other projects, except to allow your machine to crunch extra work from them while S@h sorts it's life out. Once S@h is working correctly, you should find it has accrued a "debt" from the other projects, so it will catch up with the work it "missed" during the hiccup/outage. I have managed to upload ONE WU, and am still happily downloading new work. One rig has 8 completed WU's in the upload queue, a second rig has three. Both are downloading with no issues. |

The net load is at MAX for the past few hours... Too many WU upload connections or an attack? Every completed WU causes BOINC to contact S@h at regular intervals, trying to upload. (Look under "Transfers" tab). It follows that the more completed WU's a given machine has in it's upload queue, the more attempts it will make to contact the S@h servers in a given period of time. Although each packet sent for these attempts is relatively small, there will be several hundred thousand machines, each with a growing list of completed WU's in their queues. This will generate a lot of network traffic. Best advice in such a situation is to turn off network activity for a while. (BOINC tool menu > select Network activity suspended). If all crunchers suspend network activity overnight, this should reduce contacts by approximately 33% at any given time, taking some of the pressure off. As soon as the log jam starts to move, it should clear up pretty quickly. Previous experience says about 4 to 6 hours. |

[quote] I've suspended network activity as you suggested as there isn't a reason for me to even try as I haven't uploaded anything in 24 hours anyway due to the jam. I hope it gets sorted soon. |

One of my system is out of work. I hadnt connected it for almost a day and a half, and now it is sitting with two days work which are constantly trying to upload. Switched off the network activity on all the rigs, which have a total of around 500 WUs to upload. Hope the issue gets resolved before tuesday's weekly outage. ______________ |

If it works, an indication things are returning to normal will be a shortening of your "pending credit" queue. As WU's start to return, they will "match up" with those already returned, so your total credit should begin to rise. The cricket graph (URL below) is a better way to check how much bandwidth is being used at the Berkeley end. Once you see the incoming bits reducing, you can resume network activity. Personally, I do this on one rig at a time, waiting for the queue to clear on one rig before resuming network activity on the next rig. http://fragment1.berkeley.edu/newcricket/mini-graph.cgi?target=%2Frouter-interfaces%2Finr-250%2Fgigabitethernet2_3;view=Octets;ranges=d |

... a temporary stop to AP downloads, until the cause of the anomaly can be investigated and corrected. Once the runaway download train is brought under control, uploads will look after themselves. After having a few more looks at Scarecrow's AP graphs thoughout the day, this measure gets my vote. It's all those AP units being downloaded that's clogging up the pipe. Grant Darwin NT |

I have suspended all network activity on my boxes also, as the advert (UK) say's "every little helps". What is strange though, is that although the issue seems to be with SETI, I can return data for other projects but the client refuses to request new work for any project. Same on all boxes. Rob |

... a temporary stop to AP downloads, until the cause of the anomaly can be investigated and corrected. Once the runaway download train is brought under control, uploads will look after themselves. OK, had a night's sleep and I think I've found the problem - well, the next stage in the chain. Have a look at WU 417685549. Downloaded seven times, mine is the only one which is running - every other copy failed because they couldn't download the executable file. All my recent AP allocations look like that, though this is the most extreme. Eric needs to turn on the 'proxy server' distribution channel used when new MB executables threaten to clog the pipes - or AP distribution needs to be restricted to those who have manually downloaded and installed the new Lunatics r112 optimisation for Astropulse_v5 (plug!). |

... a temporary stop to AP downloads, until the cause of the anomaly can be investigated and corrected. Once the runaway download train is brought under control, uploads will look after themselves. As usual, Richard's analysis was right on target. It's the Astropulse v5 work erroring out and being resent. To be even more specific, the errors are: <message> app_version download error: couldn't get input files: <file_xfer_error> <file_name>astropulse_5.03_windows_intelx86.exe</file_name> <error_code>-200</error_code> </file_xfer_error> Some example WUs: 417836906, 417836901, and 417768997. There are others with numbers close to those, AP work tends to get runs of contiguous numbers because there are times when the mb_splitter processes are not producing work. I've sent email to staff, hopefully they can either change the URL of the app download to something which works or cut off delivery of Astropulse v5 work. Joe |
