      Description

      See thread at http://qpid.2158936.n2.nabble.com/Strange-behaviour-for-pn-messenger-send-on-CentOS-6-td7625846.html.

      Key points:

      • pn_messenger_send will hang on CentOS 6 if the destination is not yet up
      • Works fine on Fedora 21 and 22 (by 'fine', i mean it will attempt to send, fail and move on)
      • Can be recreated by running the send.c application when recv.c is not yet running
      • Proton burns CPU as it hangs

      This effectively deadlocks our application. So far, I’ve tried compiling qpid proton c myself (both 0.8 and 0.9.1), setting pn_messenger_send timeout to 1 (it was previously -1), turning off iptables entirely and disabling selinux and rebooting but no luck.
