I'm having an issue with the ActiveConn growing on a loadbalanced smtp
setup, it seems that the connection remains in the ESTABLISHED state
until it expires. Right now the traffic through this VIP is very low
for testing purposes but I intend to load balance our smtp gateway using
LVS and I'm afraid this will cause issues (approx 1.5 million emails per
day). I'm running 2.6.10-1.770_FC3smp on the real servers and the director.
Also, I'm loadbalancing smtp on port 10225 on a different set of servers
running 2.4.21-15.ELsmp and it doesn't exhibit this behavior.
I've seen this question posted before but haven't seen any answers.
Should I be concerned? Thanks for any advice.
