Hi alessandro.gherardi@yahoo.com, Thank you for following up. I'm glad to hear that the issue has been resolved. In cases like this it is very challenging to track down the root cause. Unfortunately, there is not enough information at this time to complete an investigation to determine whether there is a bug in the server or if faulty memory or storage explains this behavior. If you experience this again, please save the data files and reopen this ticket so we can continue to investigate. Kind regards, |

Thanks. To answer your questions:
The initial sync appears to have resolved the problem. |

Hi alessandro.gherardi@yahoo.com, Thank you for reporting this issue. So we can continue to investigate would you please provide us with some additional information?
To resolve this issue, I would recommend executing an initial sync. If an initial sync is not feasible with your load and configuration, I would suggest starting the affected node with mongod --repair, Kind regards, |

Also notice that, before the upgrade, the system had been running on 3.0.4 since at least 2016-10-19, without any crashes. |
