mongodb connection loss crashes the app #133

Closed kristofsajdak closed 8 years ago

kristofsajdak commented 9 years ago

when a harvesterjs app is running, and the connection to Mongodb is lost at some point, it will crash the application with the following error message :

events.js:72 throw er; // Unhandled 'error' event ^ Error: failed to connect to [192.168.59.103:27017] at null. (/Users/CDBKRS/projects/harvesterjs/node_modules/mongoose/node_modules/mongodb/lib/mongodb/connection/server.js:555:74) at emit (events.js:106:17) at null.

Apparently this is a Mongoose level issue, the version which we are using doesn't come with a default resilience mechanism.

Applying what I found as an accepted answer on Stackoverflow : http://stackoverflow.com/questions/10873199/how-to-handle-mongoose-db-connection-interruptions

It feels like a hack, but should do for now. Did some tests where I stopped and started Mongodb, and it does reconnect automatically.

This has been fixed since our upgrade to v4.2
