At what seems like random intervals I am seeing the following error in my application logs:
RROR: exception 'Elasticsearch\Common\Exceptions\Curl\CouldNotConnectToHost' with message 'couldn't connect to host'
It's in vendor/elasticsearch/elasticsearch/src/Elasticsearch/Connections/AbstractConnection.php:320.
I can't find anything else in the logs, so any pointers on where to look for the problem are greatly appreciated.
php version info:

I know it's an old version, old server we are trying to get the client to ok the upgrade. It's Ubuntu 12.04 LTS, Elastic search client v1.3.4
The search method is"
/**
* Returns an array of products IDs for products matching the search query
*
* @param string $query
* @return array
*/
public function search($query)
{
if (is_numeric($query)) {
$return = $this->_client->search(
array(
'index' => self::INDEX,
'type' => self::TYPE,
'body' => array(
'query' => array(
'multi_match' => array(
'query' => $query,
'fields' => array('id', 'barcodes'),
),
),
'size' => '5000',
),
)
);
} else {
$search = array(
'index' => self::INDEX,
'type' => self::TYPE,
);
$words = explode(' ', $query);
foreach ($words AS $word) {
$search['body']['query']['bool']['must'][] = array('wildcard' => array(
'_all' => array(
'value' => $word.'*',
),
)
);
}
$search['body']['size'] = 5000;
$return = $this->_client->search($search);
}
$productIds = array();
if (!empty($return['hits']['hits'])) {
foreach ($return['hits']['hits'] as $hit) {
$productIds[] = $hit['_id'];
}
}
return $productIds;
}
In the elasticlog file all I have is:
