That isn't an unknown error, that is EFSM. You can figure that out by looking at the zmq.h and looking at the ZMQ_HAUSNUMERO constant. Do a little math and it is equal to EFSM. The reason you are getting this is because you are not obeying the restrictions of a REQ socket. For every send, there must be a matching recv. If you send twice in a row (or recv twice in a row) you'll get the state machine error. Please read the man page and guide for more help on REQ sockets and their restrictions. cr _______________________________________________ zeromq-dev mailing list [email protected] http://lists.zeromq.org/mailman/listinfo/zeromq-dev
