[jira] [Comment Edited] (DISPATCH-358) Intermittent crashes in
qdrouterd under load from parallel senders
[ https://issues.apache.org/jira/browse/DISPATCH-358?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15317880#comment-15317880 ]

Ganesh,
Yes, I am able to reproduce the crash without SSL also and filed another bug DISPATCH-360 for the same. I am working on refining my Java client (it currently does SSL always). Until then you can use the drivers.tar.gz from DISPATCH-343 against the three routers connected insecurely as per the config files in DISPATCH-360.
You will see the issues with the following very basic test:
$ ./recv_no_ssl -n 1 amqp://<host2>:<port2>/paypal/foo
Separate terminal:
$ ./send_no_ssl -m 4 -n 1 amqp://<host1>:<port1>/paypal/foo
Be sure to have host3 connected to the two hosts as described and run the test several times. (It will work occasionally and fail most of the times).
Then run again with host3 removed. (It will work almost always.)

> In my setup of two inter-connected routers, several senders connecting to one router while few receivers connecting to the other router, I see several crashes in the router to which senders connect. These crashes are intermittent and happen once in every 10 runs or so. I have collected the backtraces of all the crashes but do not yet have a test case that can reliably reproduce any of them.
