Source address/port – local port—Shows the 32 most recent TCP connection
attempts that were rejected, including the remote node's IP address and port, the
local port for the connection attempt, and the number of identical attempts that
have been received on that port in a row. The reason for rejection is not given. This
information may be useful in tracking down DoS attacks.
# connection-reqs rejected—Total number of connection attempts that have been
rejected
# connection-reqs pending—Current number of connection attempts that are
pending, awaiting additional data from the peer
# sonewconn calls that fail—Number of calls to sonewconn that have failed. This
statistic often indicates that either a socket connection limit has been reached or
that there was no memory to hold the socket data structures.
