[jira] [Commented] (QPID-4257) Windows+SSL: Client hang on broker
close, broker memory leak
[ https://issues.apache.org/jira/browse/QPID-4257?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13450038#comment-13450038 ]
Chuck Rolke commented on QPID-4257:
-----------------------------------
I've posted an improved patch for review. With this patch the connection closure is signalled through to clients and the clients wake up. The one-second timeout clamp is not necessary any more.

Description
-------
Based on original work by Kerry Bonin in QPID-4257. The Windows SslConnector fails to properly relay connection events causing memory leaks and client hangs.
With this patch the memory leaks are improved[1] and clients doing fetch(FOREVER) are woken properly.
Diff: https://reviews.apache.org/r/6948/diff/
[1] Windows clients using SSL or not still seem to leak about 1Kb per connection even with this patch. That may be treated as a separate issue.
