Profiling logs warning in failing to process sample due to OOM

[bruno-garcia]

Repro: This commit: bruno-garcia/cloudflare-dynamic-dns@8d19d1b (#2)

It's a rather small app. The published app (i'm testing publish) has 68 MB untrimmed. Includes the runtime (PublishSingleFile=true).

A profile actually gets captured, but I get a lot of warnings (do I miss some samples?):

Parts of the log:

  Debug: De-queueing event 9f6bc857fe10430a8b79cd2c03735dde
  Debug: Signaling flush completed.
  Debug: Successfully flushed all events up to call to FlushAsync.

On another run I saw:

Looking at the OOM exception, I think this is related to:

• Windows Service memory grows indefinitely with Tracing and Profiling enabled. #3375 (comment)

That issue was resolved.

I'll close this for now. If I encounter this again (next time I run that project) I'll reopen
