Node.js app has periodic slowness and/or timeouts (does not accept incoming requests)

Question

This problem is killing the stability of my production servers.

To recap, the basic idea is that my node server(s) sometimes intermittently slow down, sometimes resultin

Answer 1

If you need to get this working now, you can go the NASA redundancy route:

Bring up a second copy of your production servers, and put a proxy in front of them which routes each request to both stacks and returns the first response. I don't recommend this as a perfect long-term solution but it should help significantly reduce issues in production now, and help you gather log data that you could replay to recreate the issues on non-production servers.

Obviously, this is straight-forward for read requests, but more complex for commands which write to the db.
