Migrating to a new DB host - Can't connect, undefined

[Mike Kunkel]

We are attempting to move our MongoDB install to a different server. I set that up and used mongorestore to restore a mongodump from the previous server. After that I changed the config.json to point to the new host, and I tried to connect.

When running node app.js I get:

27/4 16:31 [8274] - error:  err=socketHandler, trace=, bin=undefined, sizeOfMessage=1347703880, bytesRead=undefined, stubBuffer=undefined

What am I missing here?

Can anyone help here? I've not been able to figure anything out past this point.
