Note also that rabbit will happily use as many file descriptors as it 
can get its hands on, if it thinks that will improve performance. It 
will make room for socket connections as necessary, by closing some 
descriptors for files. So getting close to the limit isn't necessarily 
an indication of a problem. What does the management UI say about the 
available *socket* descriptors?
