Hi @Kadir_USTUN
Yes MongoDB 4.4.2 - 4.4.8 was not recommended for production usage anymore due to the issues you mentioned. However I don’t think this is the cause for a WiredTiger.turtle error you’re seeing. The turtle file is a metadata for the main WiredTiger metadata file (see WiredTiger: Metadata for a complete explanation of what the turtle file contains).
In short, it’s very peculiar that two nodes have the exact same complaint about turtle file corruption. Typically these errors are generated if the hardware is having issues, but there’s not much more knowledge we can get from the logs themselves.
Best regards
Kevin
