[zeromq-dev] epgm subscriber connect error : invalid argument

[gizem güleşir]

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
