[jira] [Resolved] (QPID-7011) [Java Broker] Broker can run into
conditions when receiving of initial protocol exceeds the handshake timeout
and connection is closed due to inactivity
[ https://issues.apache.org/jira/browse/QPID-7011?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alex Rudyy resolved QPID-7011.
------------------------------
Resolution: Invalid
Investigation of the problem revealed that it is not a broker issue but a client one. It was caused by direct memory usage on the client. The GC collections were taking 5-10 seconds due to finalization of direct byte buffers. Switching back to usage of heap byte buffers in commit [https://svn.apache.org/r1727449] resolved the issue

> Key: QPID-7011
> URL: https://issues.apache.org/jira/browse/QPID-7011
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: qpid-java-6.1
> Reporter: Alex Rudyy
>
> On running performance tests for 0-9 protocol the tests can fail due to initial protocol receiving (or receiving of ConnectionStartOk) takes more time then default handshake timeout (2seconds). The issue occurs for the subsequent tests running after other tests which had cleared their test objects (queues/bindings/messages). It never happens for the first test.
> On broker side connections can be forcibly closed due to inactivity in 2 ways:
> 1) on not receiving of initial protocol

> 2) on sending ConnectionStart (It looks like created ConnectionStart frame is not put onto wire)
