------------------------------------
I made some changes to the router auth plugin to better handle this area:
https://issues.apache.org/jira/browse/DISPATCH-1269 (though these are
speculative and I never reproduced the symptoms)
> Proton Client is "stalled" during SASL handshake
> ------------------------------------------------
>
> Key: PROTON-1996
> URL: https://issues.apache.org/jira/browse/PROTON-1996
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-j
> Affects Versions: proton-j-0.25.0, proton-j-0.31.0
> Reporter: Daniel Maier
> Priority: Major
>
> Hi,
> When I try to connect with proton vertx client to an AMQP server, the client
> seems to come sporadically in some kind of "stalled" state. The logs, see
> below, look like the server just not responds anymore which cause the client
> to be stalled. There are no more logs regarding SASL handshake.
> Used server is qdrouter.
> Would it make sense from your point of view to introduce a timeout here? Or
> is the responsibility for this in the calling application?
> {code}
