Ted Ross updated PROTON-466: ---------------------------- Attachment: PROTON-446.patch Patch that fixes the problem. > Driver - Optimization causes hangs in cleanly closed connections > ---------------------------------------------------------------- > > Key: PROTON-466 > URL: https://issues.apache.org/jira/browse/PROTON-466 > Project: Qpid Proton > Issue Type: Bug > Components: proton-c > Affects Versions: 0.5 > Reporter: Ted Ross > Assignee: Ted Ross > Priority: Blocker > Fix For: 0.6 > > Attachments: PROTON-446.patch > > > Related to https://issues.apache.org/jira/browse/QPID-4853 > Often, when a connection is cleanly closed, the connection-close handshake > completes but the connector is never closed. All that is needed is for one > more connector_process cycle, but the connector never again appears in the > work list. > There is an optimization in the connector processor that says "if the socket > has accepted all of the current data for send, clear the SEL_WR flag". The > problem is that when the data-for-send is the last data to be sent on the > connection, the connector is never again processed and hangs, using resources > and keeping the socket from fully closing. -- This message was sent by Atlassian JIRA (v6.1#6144)
