System: OS X 10.9.5
Processing version: 2.2.1
The symptoms were that Processing was working fine one day, then later sketches stopped working (or sometimes would delay opening for 1-2 minutes). No errors were displayed in Processing, logged in console .err files, or reported to OS X Console. There was a repeating error in OS X Console for an unrelated service (mtmapp: MTM fs Mount server retrying...), and troubleshooting that lead to discovering that localhost wasn't resolvable. The issue was that localhost was set to "fe80::1%lo0", and IP6 routing was somehow broken. Resetting localhost to 127.0.0.1 allowed Processing sketches to work again.
