Recently we have started to have an increasing number of a particular error, where jobs fail due to "failed waiting for external process". One machine in particular has had a number of these failures, and looking at its task log it appears that its VM is frequently stopped and restarted some time later. I'd like to just remind the users that our VM doesn't like to be stopped, especially if it's done in a non-controlled way (if, for example, an external application is started which causes the BOINC manager to stop tasks to give up resources). For short stoppages it is recommended to use manager or boinccmd to pause the task, and wait for the VM to save its state before stopping BOINC. |

I do hope when we come back to life here that they return to working as good as they were for the last month (version 61.25 vbox64_mt_mcore_cms is working perfectly right now) |

In reply to Magic Quantum Mechanic's message of 7 May 2026: I do hope when we come back to life here that they return to working as good as they were for the last month I'm nor sure why we had the dip in running jobs last week. People saving energy because of the Iran crisis? Or shutting down machines because of a heat-wave? I know there was a power outage at FNAL recently, but I don't think they give us substantial resources. |
