Socket Error - ECONREFUSED
I'm having few issues with websocket connection. I'm using wss with signed certificate. It starts with following lines on the error log,
```
2017-12-03 02:13: failed to send message to miner, websocket seems to be already closed not opened
2017-12-03 02:14: failed to send message to miner, websocket seems to be already closed not opened
2017-12-03 02:14: failed to send message to miner, websocket seems to be already closed not opened
2017-12-03 02:26: failed to send message to miner, websocket seems to be already closed not opened
2017-12-03 02:26: failed to send message to miner, websocket seems to be already closed not opened
2017-12-03 02:29: failed to send message to miner, websocket seems to be already closed not opened
```
this goes on for a while and then it starts to throw following,
```
2017-12-03 02:42: socket error (domain.com:3333) connect ECONNREFUSED 127.0.1.1:3333
2017-12-03 02:42: socket error (domain.com:3333) connect ECONNREFUSED 127.0.1.1:3333

```
I'm running node-xmr-proxy on port 3333 on the same server. And then within few seconds proxy goes down with following,

```

This keeps happening every few hours and my hashrate drops. I was on a 512MB droplet with open file limit lifted. Then I created another 2 512MB droplets and tried round robin dns. each has both this proxy and xmr-node-proxy. But it still goes down every now and then. I'm not sure if I want to upgrade to 1GB droplets. Any advice will be appreciated.

PS my miners around 700 - 800
