Hi @prashant_sinha welcome to the community!

What’s your MongoDB version, and what’s the replica set topology? I believe a similar-looking issue was fixed in SERVER-40535. If you’re not using the latest version in the MongoDB series you’re using (4.2.23. 4.4.17, 5.0.13, or 6.0.2), please try to upgrade and see if the issue persists.

If you’re not using one of the supported series (e.g. 3.6 or older), then I would suggest to upgrade to a supported version, since unsupported versions will not get any more updates/fixes.

Best regards
Kevin

Hi @kevinadi
Mongo DB version is 4.2.18 . Is it required to be upgraded to resolve this issue

Hi @prashant_sinha

It’s recommended to upgrade to the newest version in the series you’re using regardless.

If you’re still seeing this issue after upgrading to 4.2.23 then we’ll know for sure that the issue you’re seeing is new and not the same one fixed in the SERVER ticket, even though superficially it looks similar.

Best regards
Kevin

I can share the bson dump as well if required to debug the issue, I do not see this issue being fixed, is there any thing which can be done currently to fix this.
