Problem

I've been using `mongoose` for a few years, but lately I'm having a lot of trouble where the connection seems to disappear. Connection Settings [code block] The Problem Mongoose just stops calling back. It doesn't emit any errors, memory/cpu is fine on my server & db, and I can connect from any other server. Restarting always fixes it: [code block] Versions On `mongoose 4.4.11`, `mongoose.connection.readyState === UNAUTHORIZED` when callbacks stop. So I upgraded to `mongoose 4.6.0` but within 4 hours the callbacks stopped again, now with `mongoose.connection.readyState === CONNECTED`. Any Ideas Any ideas how I can get this to stop happening? I'm happy to gather any more debugging info, just let me know what info to get.

Error Output

Error connecting to db: "+err); }
