Ok now I know what may be responsible for this bug : background index building. My use case is the following : The crash didn't occur before I have discovered the background indexing, and now that I don"t use it anymore, it has not happened again. |

the last 10 minutes of mongos with -vvv option are in attachment full log is too heavy for being uploaded on jira, here it is : http://fichiers.ecp.fr/get?k=2ikD4ciTLPPJJGuVMEs |

It would be good to get more verbose logs (run with --vvvvv) and more than 10 minutes of logs from before the incident. Are you able to reproduce this error? |
