| Description |
|
mongod segfaults as seen in the log snippet: Dec 19 14:26:49 abrt[3665]: Saved core dump of pid 24104 (/usr/bin/mongod) to /var/spool/abrt/ccpp-2012-12-19-14:26:38-24104 (1784872960 bytes) Around this time a number of issues and errors are seen in mongod.log which should have recovered and could be caused by possible issues in AWS or mongod itself we are currently unsure so hints here would also be great. |

Barrie, We haven't managed to replicatate this since the first occurance even with the same settings as we had previously. I think you can probably close but if we see this again we will take full logs and re open a case. | |

Hi Alister, Are you still running into this issue? Barrie | |

Alister, It looks like your open files and processes limits are too low. We recommend open files to be 64000 and processes to be 32000. These recommendations (and others) can be found in our documentation here. Barrie | |

Looks like the init script sets ulimit to 12000, do we want to increase it further? | |

Alister, Did you try increasing the ulimit? Barrie | |

Looks like the ulimit is too lower (default of 1024). |
