Actually we have the same issue with Postgres, so it really points to a bug in the node compatibility layer.

I think we'll use OTel's native integration in Deno 2.2 before releasing agian.

My hypothesis so far: we're relying on a version of OpenTelemetry than may not be supported by Deno 2.2.

How confident are you that it relates to the Deno version? Are there any other infrastructure changes that could have affected this
A 100% sure. We're doing continuous deployment. We ship one commit at a time, and the commit only upgraded from Deno 2.1.10 to Deno 2.2.11. Once we reverted, everything went back to normal.

What makes you conclude that it's memory related?
Right after deployment, graph shows memory increasing progressively. At some point connections to the DB start to drop. Then ECS restarts the containers as they become unhealthy. Rince and repeat.

Is there anything in the logs?
We didn't have logs when I posted, because it turns out that the issue breaks OpenTelemetry. We found logs by looking directly at AWS. Here it is:

To note: we ship an executable produced by deno compile.
