I just found all of my phoenix 2.0.0 miners at 0 Khash/s, and this was on multiple machines.
They were mining Eligius with p2pool as fallback. Here is a sample of the log output. Restarting the program fixed the problem. Could this be a bug in Phoenix?
In Windows this happens:

It's a bit different in Linux, I actually get a stack trace:
