- 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.
