FWIW, I think I found the root cause of all of these connections.  Two 
users are
importing large iCalendar files.  My suspicion is that each event is 
triggering
one (or more) from_addr lookups.  I have temporarily worked around it by
providing more connections at the OS level (Linux) by increasing
local_ip_port_range and decreasing tcp_fin_timeout, but long term, I have to
get the fullname and from_addr hooks to be a once and done thing.  So
suggestions are welcome :)
