homam, we haven't heard back from you for a while. If this is still an issue for you, can you please upload the full server logs? You also may want to try running repairDatabase after backing up your database files to see if that clears the specific issue you're seeing. Thanks, | ||

homam, can you also please upload the full logs for the node where you experienced this issue? We're specially interested in knowing if mongod may not have been shut down cleanly at any point. If the logs are sensitive you can upload them via scp as described above. Thanks, | ||

homam, can you tell us a little bit about the history of this collection? With what version of MongoDB it was created, if there is anything special about its history? Thanks, | ||

homam, I've moved your ticket to the SERVER project, as this is an issue with MongoDB and not with stand-alone WiredTiger. Looks like one of your files got corrupted, and accessing the corrupt records prompts mongod to shut down to avoid any further damage to your data. We'll need some of the affected files to troubleshoot this issue. Can you please upload the following files?
To upload these files privately you can use scp as follows:
When prompted for a password just press enter. This issue may also have been caused by a flaky disk, so please check your system logs and/or disks' SMART status (if applicable) for error messages about the storage layer. We'll take a look at the files you upload to determine if there's a bug in mongod that may have triggered this issue. Thanks, |
