Comment 8 for bug 689330

Ah, that's not a real issue:
you will notice that the two functions that are accessing the map are synchronized (in fact, using a synchronized data structure here would have not been enough).

I think you can close this bug.
you can try to make the lib behave better when it fails to open new files/sockets (due to the max open files limit), but this is not hugely important. (IE : give more specific errors, not NPE or "No servers are registered").
