 Qpid Proton Point to Point Hang on CentOS 6 pn_messenger_send
 -

 Key: PROTON-907
 URL: https://issues.apache.org/jira/browse/PROTON-907
 Project: Qpid Proton
  Issue Type: Bug
  Components: proton-c
Affects Versions: 0.8, 0.9.1
 Environment: CentOS 6 (both VM and native 64-bit) and RHEL 6
Reporter: Frank Quinn
Assignee: Gordon Sim
Priority: Critical
 Fix For: 0.10

 Attachments: PROTON-907-workaround.patch


 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.
