Types of errors that are possible:

• connection failure (after connection has been established)

• connection cannot be establishedtcp socket fails (or whatever the rdma equivalent is, assuming that is a detectable condition)

• missed heartbeats

• authentication errors

...

• internal error in broker, i.e. some as yet unidentified bug, misconfiguration or environmental problem

• internal error in client: same thing for client-side misconfiguration or bugs.

• Exceeded client-side limitation: a client-side queue is over-full. E.g. user has not respected flow control limits on the client side.

• Transaction related errors - not sure what the set is, probably just copy from spec exceptions.

Impact of errors:

• session no longer valid[1]

• connection no longer valid[1]

• transaction aborted

• no longer term impact, specific call simply failed

[1] May want to distinguish between amqp 0-10 session and sessions in the messaging api here. E.g. even if a particular condition kills the amqp 0-10 session/connection, that may not prevent recreating the session or reconnecting.
