             Summary: 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: 0.9.1, 0.8
         Environment: CentOS 6 (both VM and native 64-bit) and RHEL 6
            Reporter: Frank Quinn
            Priority: Critical


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.
