I was finally able to find a specific concrete weirdness (atleast I think it's a weirdness). From test-client2, I am running http_load (installed from /usr/ports/www/http_load): http_load -p 20 -seconds 1800 /home/ggong/tmp/urls The single url it is testing against is a very short page on the server. This is what I see: c206 - ggong@test-client2:~>netstat -na | grep 4670 tcp4 0 0 192.168.0.22.4670 192.168.0.10.80 SYN_SENT c207 - ggong@test-client2:~>ssh root@ts "netstat -na | grep 4670" tcp4 0 0 192.168.0.10.80 192.168.0.22.4670 TIME_WAIT c208 - ggong@test-client2:~>netstat -na | grep 4670 tcp4 0 0 192.168.0.22.4670 192.168.0.10.80 SYN_SENT c209 - ggong@test-client2:~> If I am not mistaken, this should not happen.. I'm also relatively certain the TIME_WAIT is not from a previously closed connection.. Any ideas what might cause this, or hints on how I can further investigate this?
