Connection refused - connect(2)

I got this error this evening while running my specs: Connection refused - connect(2)

I'm running under test/development and I'm using SQLite3. I didn't have this issue yesterday and my code hasn't changed since then. I looked around and people are saying that it's a DB connection problem (which would make sense). However, I'm using SQLite3 so I don't understand why it would have connection issues. I've restarted my machine, re-migrated my databases and nothing seems to work. The error comes up even if I try to do database operations manually in rails console.

I'm currently using Ruby 1.9.2 and Rails 3.0.0.

Any ideas?

are you using rvm?

It was a Sunspot issue. Thanks for the response though!
