I am crunching Theory tasks on 5 machines. With one of them I notice that after the recent Microsoft Updates (Windows 7 32-bit) there is an increased failure incidence, always due to "missing hearbeat". The bad thing is that this always happens after 10-13 hours, so a lot of CPU time is wasted for nothing :-( An example can be seen here: https://lhcathome.cern.ch/lhcathome/result.php?resultid=217623492 I experienced this problem before, once in a while. I then somewhere read that one could try to increase the CPU priority for the VBoxWrapper (via the task manager); I did this, and it helped. So this was the first thing which I checked now, but actually the priority is still set to "above normal", as I had set it before. Obviously, the problem now must be caused by something else. Does anyone have any advice what else I could try to overcome this problem? |

Have you checked for disk errors lately? You might want to update your Virtualbox to 5.2.x since earlier versions are no longer supported by VirtualBox. Version 5.2 will remain supported until July 2020, according to www.virtualbox.org Do you have anti virus and exclusions set for the directories like in Yeti's check list? |

Jonathan, thanks for the hints. I'll look into all this. |

And..once again, tons of wasted CPU: https://lhcathome.cern.ch/lhcathome/result.php?resultid=216849465 Why is this failing now? No credits? no science? |
