As I mentioned before, the failures shown in both the errors.u.c reports (and which are really confusing, I don't really trust the backtraces to be correct there, they don't make much sense) and the original backtrace, just indicate that that the server has died and the clients fail to communicate with it.
So I take this bug as a request to make the failures more graceful on the client side (as much as we can).
