         Environment: Host: Fedora 5.10.16-100.fc32.x86_64; 
gcc (GCC) 10.2.1 20201125 (Red Hat 10.2.1-9)

            Reporter: Charles E. Rolke


Adding support for the drain buffers event in qpid-dispatch reveals that the event never arrives in any of the qpid-dispatch tcp self tests. Grepping the logs shows 178 CONNECTION_CONNECTED events and 178 CONNECTION_DISCONNECTED events but no DRAIN_BUFFERS events.
