I had this failure today, that looks like a timeout, based on the test duration: 18.16s call tests/lib/yajsonrpc/jsonrpcserver_test.py::JsonRpcServerTests::testMethodBadParameters(True) Looking at the log it smells like the known race when connecting to server. Also we see: - ERROR vds.dispatcher:betterAsyncore.py:179 uncaptured python exception, closing channel Should never happen, means we did not handle exceptions in some handler. - WARNING vds.dispatcher:betterAsyncore.py:179 unhandled write event Should not happen, means that we did not implement handle_write() in some dispatcher.
