Node showing disconnected status #7
Description
Hi, I'm using this node to query my Oracle DB, and it works fine, but sometimes it just sends an error in debug tab 
and show status disconnected under nodes.
Even so, it's possible to query the db, until it stops.
If I just open, then close the related config node, then deploy it, the status change to unconnected and any query makes it connects and work again.
I'm running node-red 2.0.6 from docker and oracle-mod node 0.6.1.
