rpc_pipe_open_tcp_port() needs millisecond, not second timeout.
Fix in master and 3.6 is: 4b3fe5247a6e16b1ad9f05269e9aa00e3120e36a
This is probably also an issue in 3.4 and 3.3
Ack from here. 4b3fe5247a6e16b1ad9f05269e9aa00e3120e36a applies to v3-5-test and v3-4-test. Karolin, please pick for those releases.
Pushed to v3-5-test and v3-4-test.
Closing out bug report.
