Connection dies after a significant amount of requests

[cebe]

When inserting a massive amount of records the connection fails at some point when the system runs out of sockets:

Exception (Elasticsearch Database Exception) 'yii\elasticsearch\Exception' with message 'Elasticsearch request failed: 7 - Failed to connect to 192.168.178.50: Cannot assign requested address'

You did not set the SO_REUSEADDR flag, so after "40k -50k documents", you have forced your
system to ran out of sockets. See also http://php.net/manual/de/function.socket-set-option.php

Had the same issue, using the dev release fixed it. Would be nice to see it in release.
