Description
Tom Tracy
2011-08-18 18:33:12 UTC
The packet size should state to be 512K or greater Which non-RT kernel was used? And what is the client used? Some standard test found in the qpidd packages? What command line was used with it? On the broker side,
/usr/sbin/qpidd --data-dir /var/lib/qpidd --auth no -m no --log-enable=info+
Client side

Tried reducing the number of queues (qt) to default of 4 and still see the same issues

With the 2.6.33.9-rt31.66.el6rt.x86_64 still see the same issue [root@perf48 ~]# /usr/sbin/qpidd --data-dir /var/lib/qpidd --auth no -m no 2011-08-18 16:06:48 notice SASL disabled: No Authentication Performed 2011-08-18 16:06:48 notice Listening on TCP port 5672 2011-08-18 16:06:48 notice Broker running 2011-08-18 16:12:10 error Error reading socket: Bad address(14) This is too old, out of scope. Perhaps the test is worth snagging |
