Hi @maxday,
after switching to the new Datadog Extension v22 with the release of serverless-plugin-datadog v5.0.1 we do see errors again (Unable to create StatsD client / Unable to bind to an available socket / too many open files & error creating socket), some of them we've seen first time with #78:

as well as the following:

DD_RUNTIME_METRICS_ENABLED: false is still set.
Do you maybe have any idea what we're doing wrong or what have changed?
Thanks and all the best
David
