slaveClient not able to resolve to an end point

Hi ,
I am using redis-sentinel with three sentinel server and 8 slave with one master.

Setup

8 machine each has redis 2.8.14 , out of these 3 machine having sentinel. They are monitoring a single master at machine 1.

Here is the piece of code i am using to get connected to a slaveClient

var endpoints = [
{host: 'host1', port: 26739},
{host:'host2',port:26739},
{host:'host3',port:26739}
];

 var opts = {}; // Standard node_redis client options
 var masterName = 'mymaster';
 var redisClient = sentinel.createClient(endpoints, masterName, opts);
 var slaveClient = sentinel.createClient(endpoints, masterName, {role: 'slave'});
 slaveClient.on("connect", function () {
 console.log("hey")

 console.log(redisClient.server_info)
});
slaveClient.on("error", function (err) {
console.log("err",err )
});

Most of the time it prints the "hey" and server_info but few times it neither print the "hey" nor server_info infact the entire node process hangs without printing any error.

Is there any thing i am doing wrong ?

All looks fine to me. Are you sure the master and sentinels are responsive when it hangs etc?

Yups master and all three sentinels are responsive. Just a quick question what will happen if a slave is down or unreachable ?
