Today I'm having problems to report finished tasks because of the gateway timeout error.

I'm not able to get or report any work due to timeouts. BOINC is in a no communication state effectly, the server requests no communication for 2 hours, at the 2 hours, it tries once but there is gateway timeout, then it wait 3 hours etc. I increase my work buffer from 0.1 to 1 day, hopefully this will lower the load. |

Lets see how it goes over a longer period, but its not initally so good, each host got about maximium work (58 WUs) and this morning they are all completed but there was no contact with the servers in the ~24hr so they are now idle waiting for a sucessful server communication. |

Today rather normal except the longer existing results request from a host. Seems to me a bad indexed DB. Reporting tasks: 15 May 08:10:36 Reporting 1 completed tasks 15 May 08:10:41 Scheduler request completed 15 May 09:15:42 Reporting 1 completed tasks 15 May 09:15:44 Scheduler request completed |

Uploads/downloads seem to be working now. At least I managed to upload the queue that has built up overnight and got some fresh CMS tasks.

10 is the server cap for Theory tasks if this is what you request. |

My 2 less powerful computers got a connection. The other still are stuck, with timeouts, maybe they got blocked as they are contacting the server too frequently? |

Just my noticing. When I try to open page with tasks for my computer, I get http timeout. Maybe there are to much rows, maybe you lost some index or some problems with fragmentation of table |

I got that today but tried about 10 minutes later and it worked. Let's crunch for our future. |

In general my computers can not even contact the project any more if I leave them. As Saturn said if I set to NNT then they will report work and there is a contact. Even though I set the work buffer to 1 day, for my fastest computers the limits of 10 Theory, 8 CMS and 40 ATLAS are not enough work for 1 day so they continue to request work after they are done in so they start to request work after a short period of time where the Deferred for: time , Req by project start to appear. I'm not sure what I can do to not conact the servers so often but maintain consistant work. |

In reply to Toby Broom's message of 22 May 2026: I'm not sure what I can do to not conact the servers so often but maintain consistant work.I am afraid there is not much YOU can do until the project team finally gets the problem solved. No idea when this will happen - maybe it will not happen at all :-( |
