Hmm my Linux machine is once again struggling to get work, all other machines have full caches. It is a really odd issue. Since I wasn't having any issue I did some testing changing my settings all around and I was still not running into the issue. I guess whatever the issue plaguing some users is there is another part related to it that I can not reproduce.

It may (or may not) be related to the BOINC manager version and/or whether or not you have an application for AP installed, or not. Grant Darwin NT |

Sorry, I thought you were speaking about the problem getting new units after the tuesday maintenance. As Grant says, check your BOINC version. If you are running several computer inside a LAN, make sure you have a static IP. Also make sure you don't send server 'computation error' wu or the server will not send anymore wu for a while (check 'Errors' in your web interface). Also it would be interesting to know who has the same problem as you and check your relative configuration. |

It is a really odd issue. Since I wasn't having any issue I did some testing changing my settings all around and I was still not running into the issue. The client version could be a variable. I was using 7.6.23 before switching to 7.6.33 on my Windows hosts. I currently have 5 Windows hosts with 7.6.33 & 1 Linux AWS host with 7.4.42. They are all configured with an app_info.xml that include these apps: 8130144 MB: CPU, AP: none, Venue: default 5837483 MB: CPU & ATI, AP: ATI, Venue: home 7324426 MB: Nvidia, AP: IGPU, Venue: home 8146263 MB: iGPU & Nvidia, AP: none, Venue: school 7421701 MB: CPU, AP: CPU, Venue: default 8115499 MB: CPU, AP: none, Venue: default My venues settings are: Venue default home school work Use CPU yes no no yes Use ATI GPU no yes yes yes Use NVIDIA GPU no yes yes yes Use Intel GPU no yes no yes Then I cycled through these options Test 1 2 3 4 5 6 AstroPulse v7: yes no yes yes no yes SETI@home v8: no yes yes no yes yes Other apps: no no no yes yes yesNote: Deselecting both MB & AP will set the selection to (all apps). Selecting MB or AP, saving, and then selecting the 2nd app will not set the selection to (all apps). ¯\_(º¿º)_/¯ For each test cycle I would change the setting on the site & update the client to ensure it had the latest config. Then I would wait and see if the tasks on the host would go down. Test 1 & Test 4 resulted in no work being sent. As we have little to no AP work and the Other apps function is still broken. I never got a "project has no tasks" message for those two tests. Just the "No tasks sent" "No tasks are available for AstroPulse v7" messages. Test 2, 3, 5, & 6 resulted in work being sent or a "This computer has reached a limit on tasks in progress" message. As of this moment my venue settings are: Venue default home school work AstroPulse v7: no yes no yes SETI@home v8: yes yes yes yes Other apps: no no no no SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

. . Yep a truly strange bird is this problem. It isn't limited by global location, OS, Version or CPU/GPU logistics. Yet it only affects some users. A head scratcher for sure. Stephen ?? |

. . This issue is affecting Grant and several others more than me. I have experienced it on a few occassions where the effects lasted for several hours (up to nearly a day once), but mostly I am OK. It is the variability of the occurrence that is most puzzling. Stephen ? |

. . To me it seems to be related to the "Other Apps" function breakdown in that the symptoms emerged about the same time. But since I did not myself use that setting I may be wrong and that malfunction may have occurred earlier. Stephen ¯\_(º¿º)_/¯ {sorry for pilfering but I liked it :) and cannot make it myself} |

Wait... you stole my ASCII art! RAWR! (╯°□°)╯︵ â”»â”â”» The issue does seem to have started for some users at the same time. With the supposed spaghetti code in the scheduler I wouldn't be surprised if it turned out to be something weird and seemingly unrelated effecting those users.

I'm curious if what I do to get tasks on my i7 Linux when it has a little trouble - maybe once a day it will run down to 60-40% of cache before filling, but never seen it actually run out because of this. When it starts running low I use BoincTasks (obviously remotely) and suspend waiting GPU tasks, then enable the last 3-5 tasks that I received (I've only had these for a short time) and wait for them to run. Then onto adding a few resends or shorties to run while waiting for the 5 minute timer to expire. Then after 5-20 minutes (doesn't seem to matter) enable the rest of the tasks just as a upload is happening. Then poof I get a full load. ... It always works for me as long as the server is not in a drought. Which makes me wonder if it isn't something in the upload script that me sending tasks out of order is making it reload my profile, or the fact that a upload is in progress causes something else to happen. I don't know. All I know is that I can get give me tasks without toggling the settings. Can someone else try this? |

How many people affected by the problem are running the rescheduler? I do. Could that cause the "out of order" problem Brent mentions? Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

I manually run the rescheduler on my i5 w/750Ti and never have trouble with it. |

Lately I've been able to wake up the server by just hitting the Update button twice in quick succession. As soon as the first request is finished, hit it again. Usually this reminds the server the Host is requesting Hundreds of Thousands of seconds of work, and the next request sends tasks. To me it seems the server is just not registering the Host is requesting work, and needs to be reminded to send work. Look at the Log from this post, https://setiathome.berkeley.edu/forum_thread.php?id=81086&postid=1851867 It's pretty obvious the Host is working as expected and sending work request with the amount going Up with each request. The server seems oblivious to the fact the Host is requesting Hundreds of tasks. I don't see how anyone can blame the Host in this case, the server is just ignoring the work request. The last couple of days I haven't been having any problems, but, I'm sure that will change at some point. |

I was using Boinc 7.2.42 when this started, upgraded to Boinc 7.6.33. No Change. No idea what the common factor is. Very, very weird! Bruce |

Well that kind of puts a kibosh on my theory. And TBar, yes that is the same kind of thing I see in my log when I have the log options set to show how much work is requested. Just the same scenario, I request thousands of seconds of work and the response from the server is nada, nothing sent. I will have to try the trick of just hitting Update a couple of times and not actually flip Applications on and off to see if I can wake the server up that way.

Usually this reminds the server the Host is requesting Hundreds of Thousands of seconds of work, and the next request sends tasks. To me that indicates the server didn't complete the request even though it responded with 0 tasks the first time. The second 'quick' request should get a 'Request too soon' (and back off restart) reply if it completed the first request. Wait, do you mean make the second request before the first one responds? |

Test 1 & Test 4 resulted in no work being sent. As we have little to no AP work and the Other apps function is still broken. I suspect when this issue is fixed, then those of us having issues getting work will be resolved along with it. Grant Darwin NT |

I think for Brent the out of order returns is the solution not the problem. If it were consistently so then anyone using the rescheduler would have no issues. Stephen :) |
