How does the number of TIME_WAITs compare to the maximum number of
open files/sockets per process?  Are you running out of socket
connections while waiting for TIME_WAIT to expire?  TIME_WAIT
period is supposed to be four minutes, but can usually be configured
for a shorter interval ( I've heard of it being set to as little as
30 seconds in some cases ).  Another tunable to consider.  You must
be attempting to sustain a terrific transaction rate to see that
many rejections per second.  -rs
