Mongodb Error : pool is draining / pool destroyed


I have a MongoDB server on a local network and a flow with a node-red-node-mongodb node, all works fines, but if for certain amount of time the mongodb server aren't available i am starting to get the following error : "MongoError: pool is draining, new operations prohibited" (update() node), then once the mongo server up/available again i am getting the "MongoError: pool destroyed"(find() node) error.

The problem is that "node-red-node-mongodb" node doesn’t reconnect.
Any suggestions?

Thanks very much.
