Susan Hinrichs reassigned TS-5092:
----------------------------------
Assignee: Susan Hinrichs
> ATS handling of too many concurrent streams too agressive and maybe out of
> spec
> -------------------------------------------------------------------------------
>
> Key: TS-5092
> URL: https://issues.apache.org/jira/browse/TS-5092
> Project: Traffic Server
> Issue Type: Bug
> Components: HTTP/2
> Reporter: Susan Hinrichs
> Assignee: Susan Hinrichs
>
> This issue was identified while debugging new errors seen by an internal team
> after they enabled HTTP/2 in their client. On the backend, they saw an
> increase in the cases were ATS sends the origin the POST header but no POST
> body and then closes the connection.
> With the addition of Error() messages we were able to see a case where the
> client is trying to open the 101'st stream on a session. This is beyond the
> 100 max concurrent stream limit, so ATS shuts down the session which kills
> the previous 100 streams.
> A closer reading of section 5.1.2 of the spec
> (https://tools.ietf.org/html/rfc7540#section-5.1.2) indicates that this
> should be a stream error and not a connection error. Bryan Call, Masaori, and
> Maskit confirmed this interpretation. Maskit also noted that the other error
> case in the current createStream method must be treated as a connection error.
> Presumably the client library is expecting the refused stream case so it can
> try again later.
