Now that we are running in production we are experiencing all the failure modes out in the wild. Around 61% of the failing tasks are VMs that fail to boot and are killed by the heartbeat mechanism. There was not enough information in the stderr logs to understand the issues so Rom is working on some improvements to the vboxwrapper. A new version was deployed here on Friday and we already have some result in :). http://lhcathomedev.cern.ch/vLHCathome-dev/result.php?resultid=201302 http://lhcathomedev.cern.ch/vLHCathome-dev/result.php?resultid=201380 http://lhcathomedev.cern.ch/vLHCathome-dev/result.php?resultid=201377 http://lhcathomedev.cern.ch/vLHCathome-dev/result.php?resultid=201185 http://lhcathomedev.cern.ch/vLHCathome-dev/result.php?resultid=200884 The error message from VirtualBox is: ERROR [COM]: aRC=E_ACCESSDENIED (0x80070005) aIID={f30138d4-e5ea-4b3a-8858-a059de4c93fd} aComponent={MachineWrap} aText={The object functionality is limited}, preserve=false aResultDetail=0 Does anyone have any ideas about what the causes may be? |

One possible solution might be to reinstall Vbox with admin rights. Please uninstall vbox first and after reboot use "ccleaner" to clean up registry. The reinstall vbox. If that works, please post here. |

Do you have any of those errors appearing on machines with lots of memory ? All your examples could easily be close to the edge and drop off when they try to start ! |

This one had only fails for several months. Last valid result in January. http://lhcathomedev.cern.ch/vLHCathome-dev/result.php?resultid=201302 http://lhcathomedev.cern.ch/vLHCathome-dev/result.php?resultid=201380 http://lhcathomedev.cern.ch/vLHCathome-dev/result.php?resultid=201377 This is hardly suitable to demonstrate the case. |

Rasputin42, Thanks for the suggestion. I have sent PMs to those involved. Hopefully they can try this and will get back to us with the result. |

The hosts involved in the tasks posted have either 4 or 6GB. Should be enough for one task. |

Rasputin42, Looking at the stderr_txt for the completed tasks shows that the VMs did not start and were just idling. Now with the heartbeat mechanism they will error out after 10 mins as a failure with no credit being assigned. |
