Sorry to be the bearer of bad news, but I'm getting these as of today as well. Unit after unit failing with "207 (0x000000CF) EXIT_NO_SUB_TASKS" |

See: https://lhcathome.cern.ch/lhcathome/forum_thread.php?id=5309&postid=41635 The case is still open. |

Actually, that is quite encouraging. It means they are doing a ground-up fix. No more empty work units. Even a native version. |

CMS is back and working, for the moment. |

I thinks as long as Ivan does not give his "go ahead", crunching CMS tasks does not make a whole lot of sense. There still seems to be a problem (or more than one) that has not been resolved :-( |

Hello. Is CMS running fine now? |

Hello.yes, here it's been running fine for several days now. So let's keep our fingers crossed :-) |

Just gut a couple of errors that point out the CMS subtask queue might be empty. |

Meanwhile, the tasks queue is empty; which indicates that the automated stopping of tasks download in case of empty jobs queue works :-) Nevertheless, it would be nice to receive more CMS work again :-) |

https://lhcathome.cern.ch/lhcathome/server_status.phpthis is exactly what I was referring to. Too bad. So we'll see when new tasks will be available again. Hopefully soon. |

Yes, sorry, we seem to be having a WMAgent problem again. It might be related to an "intervention" (i.e. code update) that occurred yesterday -- unfortunately I only ever get notified of these post facto. Our agent needs some manual tweaks when it's restarted and these may need to be re-applied. I mailed several people who can do a kickstart on the agent last night, but no response yet. It's August; I know at least one of them is on holiday. At least the automatic stoppage of the queue worked. The WMStats agent monitor reckoned that jobs were still running but with this and other indications I now realise that this is false, it just took me a while to look at other indicators. Sorry for the delay, I await developments.  |

Actually, on looking more closely, I may have been a bit too harsh on the WMCore developers. This suggests the problem pre-dates the intervention: agent last updated: 2020/8/18 (Tue) 16:01:14 UTC : 41 h 51 m There was a general failure of monitoring software across the CERN network on Tuesday, it may have played some part in the problem. |

OK, looks like an upgrade incompatability. If you can follow it: https://github.com/dmwm/WMCore/issues/9876 |

One of the capables restarted the agent. The monitor still insists there is a problem, but other indications are that jobs are available again. I'm keeping an eye on it as much I can. |

Monitors are making sense now. I have a bad network connection so it's hard to keep right up-to-date. |
