We currently do: ``` } else if (!strcmpstart(line, PROTO_SMETHOD_ERROR)) { if (mp->conf_state != PT_PROTO_ACCEPTING_METHODS) goto err; parse_server_method_error(line); goto err; ``` which means that we destroy managed proxies that were supposed to spawn multiple transports but failed to launch one of them. I think we should log a warning, but keep the managed proxy around. Some transports are better than no transports; and the warning message should hopefully prompt the user into fixing the issue.
