Intermittent SSL Errors

[erudite-chimp]

I'm getting similar errors as described in issue #67 and am wondering if there's a reason why these could be happening and any recommended way to deal with them?

My keen php client setup is pretty vanilla:
$keen_client = KeenIOClient::factory([ 'projectId' => $project_id, 'writeKey' => $write_key, 'readKey' => $read_key ]);

The only thing I can think of is that somehow either cURL on our end or the keen.io endpoint is choking on the throughput of many requests being sent at the same time and that I should make use of Guzzle's backoff plugin to retry failed logging attempts?

Any thoughts on how to troubleshoot this, or any solutions to this problem would be appreciated!
