On only one of my 4 computers, several of the tasks fail with "Validate error" and the Stderr output has the following error: Transform executor raised TransformValidationException: EVNTtoHITS got a SIGABRT signal (exit code 134); G4 exception at line 3445 (see jobReport for further details) Here are example of such tasks: https://lhcathome.cern.ch/lhcathome/result.php?resultid=150102272 https://lhcathome.cern.ch/lhcathome/result.php?resultid=150089802 https://lhcathome.cern.ch/lhcathome/result.php?resultid=150085059 https://lhcathome.cern.ch/lhcathome/result.php?resultid=150081883 Anybody has an idea of what could cause the error? Should I just reboot the computer to see if it goes away? We are the product of random evolution. |

There is some strange stuff in the log: 2017-07-01 07:16:44 (19104): Guest Log: CCopyoipnygi nign piuntp ufti lfeisl eisn tion tRou nRAutnlAatsl.as 2017-07-01 07:16:44 (19104): Guest Log: CCopyoipnygi nign piuntp ufti lfeisl eisn tion tRou nRAutnlAatsl.as. It looks like two tasks are running at the same time inside the same virtual machine. I've seen this before but never figured out what causes it. Can you try a reboot to see if it helps? |

I have seen several of those also. Here's one that failed with messages showing three times. https://lhcathome.cern.ch/lhcathome/result.php?resultid=150209806 The task gave also the error 65 and ran only for about 15 minutes. The host in question had finished one task before that successfully and then one just after that. I have increased the memory from the default settings.

Here's one failed task single core task https://lhcathome.cern.ch/lhcathome/result.php?resultid=150347204. It has some of the lines in stderr repeated 7 times. The memory was set to 4500 MB. This one didn't have any error messages though.

There is some strange stuff in the log: I don't think this is coming from 2 tasks running. The output is coming from the same procID 19104, so I think this is a minor wrapper problem filtering Guest.log data needed for the stderr.txt from VBox.log. |

On only one of my 4 computers, several of the tasks fail with "Validate error" and the Stderr output has the following error: You may try a project reset and delete remaining trash (like old vdi files) from the slots directory. Then restart your host and request a fresh WU. |

Can you try a reboot to see if it helps? I have rebooted the PC and it solved the issue. It is not the first time it occurs on that computer specifically and I don't remember seeing G4 error in any of my other 2 computers. Strange... You may try a project reset and delete remaining trash (like old vdi files) from the slots directory. Next time it occurs, I will try that suggestion instead of rebooting the computer. I don't think this is coming from 2 tasks running. The output is coming from the same procID 19104, I have seen stderr.txt logs with lines repeated multiple times and / or intertwined several times in the past. I also do not think it is linked to a task failure. We are the product of random evolution. |
