Gonzalo sorry for being vague. I was running local_lat the code is as
follows, as per the test:
String bindTo = args [0];
int messageSize = Integer.parseInt (args [1]);
int roundtripCount = Integer.parseInt (args [2]);
ZMQ.Context ctx = ZMQ.context (1);
ZMQ.Socket s = ctx.socket (ZMQ.REP);
// Add your socket options here.
// For example ZMQ_RATE, ZMQ_RECOVERY_IVL and ZMQ_MCAST_LOOP for
PGM.
s.bind (bindTo);
After this code, I'm able to see the app make the connection with the
socket, however;
for (int i = 0; i != roundtripCount; i++) {
byte [] data = s.recv (0); <<<<<------- this thread just
sits here blocking
I've also tried the same code in the C++ debugger, and the thread blocks on
zmq_recv(). FWIW.
Thanks,
G
