Upgrade to Deno 2.2 caused an outage

Today, we upgraded from 2.1.10 to 2.2.11 and this caused an outage. Although we have extensive observability, there is no indication of what could have been the cause of it. The only things we know is that:

1) We are certain this is related to the Deno version, as we have reverted this only
2) Whatever it was, this caused high memory pressure

I don't even know where to start from.
