>From the user list (acartcat cartwright_and...@cat.com): > I get the following error in the broker, looks like the same error as > QPID-5033. [...] > 2016-05-26 05:22:23 [System] error No IO buffers available: getQueuedBuffer > with empty queue. Debug data: 0 1 0 3 0 0 1 [...] > This can be triggered on demand using: > qpid-send -b ssl:XXXXXXXX.com:5671 --connection-options {protocol:amqp1.0} > -a testerq --content-string=hello --messages 200 In my testing, qpid-send must also be Windows based. I do not see the error if it is sent from a client running on Linux. This error is caused by the SChannel driver generating (valid but useless) empty SSL packets when a zero length write is requested from the codec on the client side. On the server side, these are processed and empty read callbacks are generated, even after close. The WSAENOBUFS happens as a side effect of recursive calls to sslDataIn while processing adjacent empty packets. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@qpid.apache.org For additional commands, e-mail: dev-h...@qpid.apache.org
