This issue was originally reported in DISPATCH-1895 at
[https://travis-ci.com/github/apache/qpid-dispatch/jobs/461797267]
There the problem was stated as a test hang in system_tests_tcp_adaptor. Test
orchestration failed when it was creating the first router
* _wait=true_
* Router subprocess is started
* Test frameworks waits for all ports to accept a TCP connection
Due to the error the http listener port went dead. The test timed out waiting
for the http port to come up.
The diagnostic logs quoted here were not available from the travis-ci system
but were found after some other system setup produced the same error.
