Hi, I am using zmq 3.2 in C, compile with g++ (Ubuntu/Linaro 4.6.3-1ubunutu5) 4.6.3, platform Ubuntu 12.04.1 GNU/Linux, kernel 3.2.0. I use publisher-subscriber sockets with epgm. Every libzmq calls have error checking conditions implemented in my program. I have a publisher and subscriber, publisher binds to the address : "epgm://eth0;224.0.0.251:5556" .
In subscriber code: zmq_connect (subscriber, "epgm://eth0;224.0.0.251:5556"); causes an error 'Invalid argument' . I don't get this every time but, according to my observation; generally after successive runs (happens at 10% of total runs approximately ). I am wondering whether I am using wrong or reserved multicast address, if it is so, why I am not getting this error at every run ? Thanks in advance for any help. Best whishes, Gizem
