EncodedBodySize overflow

[kruskall]

According to the specification, EncodedBodySize must be a number.

As part of the ops KPI review we've been investigating the following errors in ecs logs:

decode error: data read error: v2.spanRoot.Span: v2.span.Context: v2.spanContext.HTTP: v2.spanContextHTTP.Response: v2.spanContextHTTPResponse.EncodedBodySize: readUint64: overflow, error found in #10 byte of ...|":184467440737095520|..., bigger context ...|:{"transfer_size":299,"encoded_body_size":18446744073709552000,"decoded_body_size":0}},"destination"|..

It seems 18446744073709552000 is bigger than the maximum int64, thus not a valid value for the encoded body size, making the ingestion fail in apm-server.

Hi @kruskall,

Thanks for raising this!

I have a few questions:

• Do we know the number of occurrences of this error?
• Is this related to any SDH?

I'm asking those questions to know the level of priority we should assign to it

Cheers,
Alberto

Thanks for the quick response!

Do we know the number of occurrences of this error?

~300k hit last week, happening on several clusters

Is this related to any SDH?

Not that I'm aware
