Description

When running the cifar10 example:
$./singa -model=examples/cifar10/model.conf -cluster=examples/cifar10/cluster.conf

I will sometimes get following error:
F0521 16:20:56.078801 39822 socket.cc:29] Check failed: zsock_connect(dealer_,"%s", endpoint.c_str()) == 0 (-1 vs. 0)

Rerun or recompile could solve this problem.
It is hard to track the error, so need further investigation.
