I have seen this happening in the following two scenarios :
(1) server exits before the client - The client prints the following errors and 
stays there
client DISCONNECT EVENT...
cq completion failed status 5
client: post send error 22
(2) client exits before the server - The o/p is same as what you get.

This behaviour is because of the way cm_thread() and cq_thread() functions are 
written. I have coded a fix for this. Will send it tomorrow after some more testing.

You will be able to kill only the rping process. If you look at the 'ps ax' 
output you will see that lt-rping is in the 'D' state. Hence the bind error.
Only reboot helps
