I guess nobody mentioned the obvious thing to check: Make sure
TCP keepalive is turned on.
sysctl net.inet.tcp.always_keepalive=1
Thanks Matt.
I also thought that a keepalives were not running and sessions just
stuck around forever, however I do have:
net.inet.tcp.keepidle=900000
net.inet.tcp.keepintvl=30000
net.inet.tcp.msl=5000
net.inet.tcp.always_keepalive=1 (default)
I believe keep idle was defaulted to 2hrs, I changed it to 15 minutes
with a 30 second tick... I still found FIN_WAIT_1 sessions stuck for
several hours, if not infinite.
Nonet he less, I have a new server up running 7.0-p1, I'll be pumping
a lot of traffic to that box soon and I'll see how that makes out.
