Hey @kostaspap,

Thanks for reporting, we will assign someone shortly to look into this

In the meantime, could you try using v66 and let me know if the issue persists?

Thanks for the quick response.

I didn't see anything related to the issue in the release notes for v66, but I will try it and report back if I see an improvement.

It's worth nothing that I haven't been able to reproduce easily, it seems to happen at random times for us.

So, in the v66 release notes we only publish the relevant changes for Serverless in the Go side, some of those other bug fixes you might find them in the attached Datadog Agent tag – I know it's quite confusing, sorry about that! Since this problem seems to be affecting both Serverless, and their side, that's why we probably didn't announce it here.

I've already contacted the teams who own the change on the Go Agent side so we can see what might be happening there!

Thanks for the reply.
