Obviously due to the reasons described by Ivan above, yesterday evening I had quite a number of tasks that failed after about 10 minutes (which I noticed only some minutes ago, having been away). Same, I guess, was definitely true for all other crunchers. What exactly is this WMAgent doing? Why does it fail that often? |

Message from Laurence, "Next week I will implement the automatic shutdown of tasks as a priority." It may be that CMS (and possibly Theory) hit the break and are now unable to release it. Server Status: 10 CMS, 0 Theory (Task data as of 30 May 2017, 7:32:12 UTC) |

Message from Laurence, "Next week I will implement the automatic shutdown of tasks as a priority." We do seem to be still sending jobs, despite that status report. All my monitors report over 900 jobs in progress. |

We do seem to be still sending jobs, despite that status report. All my monitors report over 900 jobs in progress. Right. According to the server status page there are 6308 "tasks" in progress. I personally prefer to call them "work units (WUs)". This means on volunteer's hosts there are 6308 virtual machines that, once running, request "jobs" (currently 900) via the WMAgent. Those "jobs" are unfortunately not visible on the status page but here. The current situation differs from other error periods in that point that now there is a lack of WUs whereas "normally" there is a lack of jobs. |

It may be that CMS (and possibly Theory) hit the break and are now unable to release it. Correct! A false positive but now fixed. |

Number of running jobs is falling. Can't see any reason yet (other than that it's Friday...). It looks like a cvmfs problem; the mapping of the site-config is wrong; Laurence's is mapping to T1_CH_CERN (which doesn't exist) instead of T3_CH_Volunteer: http://lfield.web.cern.ch/lfield/finished_1.log Beginning CMSSW wrapper script slc5_amd64_gcc462 scramv1 CMSSW Performing SCRAM setup...

my latest CMS task started 1 hour ago, and so far, it seems to work fine |

It may be my cluster that has fallen over. Won't be able to check until tomorrow. |

according to this: https://lhcathomedev.cern.ch/lhcathome-dev/cms_job.php CMS jobs still below 400 - whereas they were over 1000 two days ago. |

according to this: It looks like Laurence's cluster runs 600 jobs/h while all other users worldwide run 400 jobs/h. :-) |

according to this: well, what though does account for the sudden drop from around 1000 jobs to less than 400 jobs on June 9/10 ? |
