TCP failure in PHP7 Ubuntu 16.04

[bellom...@gmail.com]

Hello, I was trying to use Phirehose in my Ubuntu 16.04 with PHP7 . It worked on my Ubuntu 14.04 and PHP5.6 
but now, it doesn't connect to stream. And it doesn't show any error... this is what it says:

```
[08 Nov 2016 - 00:16:05] (streaming_monitor_generic_crawler) Phirehose: Resolved host stream.twitter.com to 199.16.156.20

[08 Nov 2016 - 00:16:05] (streaming_monitor_generic_crawler) Phirehose: Connecting to ssl://199.16.156.20, port=443, connectTimeout=5

[08 Nov 2016 - 00:16:05] (streaming_monitor_generic_crawler) Phirehose: TCP failure limit exceeded with 21 failures. Last error:
```

Do you know if it has some compatiblity issue with 16.04 or PHP7 ? 
It might be not a compatibility problem, though. 

Any idea?

Seeing the same issue after upgrading to OS X Sierra. The PHP version in my case is 5.6.27. Feels like this issue may be specific to certain versions of PHP?

Yes, just confirmed, downgrading to PHP 5.5 fixed the issue. So, some kind of incompatibility with later versions of PHP, it seems.

did you make sure that php-curl is installed?

apt-get install php-curl -y
