Ted Ross created DISPATCH-2262:
----------------------------------
Summary: Edge/Interior connections can half-fail in real
multi-cloud environments
Key: DISPATCH-2262
URL: https://issues.apache.org/jira/browse/DISPATCH-2262
Project: Qpid Dispatch
Issue Type: Bug
Components: Container
Affects Versions: 1.17.0
Reporter: Ted Ross
Assignee: Ted Ross
Fix For: 1.18.0
See PROTON-2440 for context.
The configured keepalive on edge-to-interior connections can fail to provide
protection from connection loss. This results in half-failed connections where
the edge sees connection failure and re-connects and the interior sees nothing
and accumulates multiple connections from the same edge.
This is a serious problem because the interior will attempt to forward
deliveries across these dead-but-seemingly-alive connections resulting in lack
of message delivery.
The solution proposed in this issue is to work around the problem by
introducing an application-level keepalive for edge-to-interior connections.
