Ah - brilliant. That fixes it - thanks! One follow up question, if I try to change the semantics so the client sends asynchronously, it doesn't seem to work.
In the round-trip example http://zguide.zeromq.org/c:tripping - they do a loop with both synch and async sending. If I try the same, the synch req/rep works, but the async does not. Here's my async function. void comm_send_asynch(int cnt, bool debug) { printf("Asynchronous round-trip test...\n"); int requests; int64_t start = zclock_time(); for (requests = 0; requests < cnt; requests++) { int ret = zstr_send(client, "Hello"); if (ret != 0) { if (debug) { dumpError("zstr_send", 115); } } } for (requests = 0; requests < cnt; requests++) { char *reply = zstr_recv (client); if (debug) { printf ("\n\treceived: %s\n", reply); } free (reply); } printf("\n\t%d calls/second\n", (1000 * cnt) / (int) (zclock_time() - start)); } When it gets to the async loop, the program outputs: Asynchronous round-trip test... zmq error: : Unknown error: 156384763 zstr_send (line 115) returned errno Unknown error: 156384763 I seem to receive the first reply from the server, but (null) thereafter. received: Hello received: (null) ..and finally this: Floating point exception: 8 Any idea what is wrong with the async req/reply ?
