Please try the recommendation here:



Hi @hari_dba, did you try adjusting the max locked memory setting to the recommended value of unlimited per the SERVER issue @jbalint shared?

If you are still having issues, please confirm your versions of MongoDB server, O/S version, and output of
<relevant ulimit command to confirm what that setting should be>

In case you have any doubts, please feel free to reach out to us.

Thanks and Regards.
