---------------------------------------
Maybe the dependency on libwebsocket can be updated to something >= 4.2.0 where
the issue seems to be fixed?

> 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.
