The issue is caused by the way the socket paths are constructed in the tests,
{code}
string socketPath = path::join(
sandbox.get(),
"mesos-io-switchboard-" + UUID::random().toString());
{code}
The lengths of the components are
* sandbox path: 55 characters (including directory delimiters),
* {{mesos-io-switchboard}}: 20 characters,
* UUID: 36 characters
which amounts to a total of 113 non-zero characters.
Since the socket is already created in the test's sandbox and only a single
socket is created in the test, it appears that it might be possible to strip
e.g., the UUID from the path to make the path fit.
