Subject: tcp retransmisison on lo? 2007-03-20 - By John Haxby
Back Hello All,
We have a very strangely behvaing system -- for no good reason mail delivery through sendmail grinds to a halt, there's nothing apparently wrong anyway except for two things -- haven't seen anything not blocked in read(2) or select(2) and wireshark was reporting TCP retransmissions of the sendmail "354" message on the loopback device, lo which seems rather odd.
Anyone come across this, or something like it?
