I have my mailservers setup as realservers in my LVS-DR network. It works well with the exception that after some amount of time (a few hours usually) the remote clients begin getting messages that they are unable to connect to mail.domain or smtp.domain (these resolve to the VIP of LVS-DR). When I try and telnet to the mail ports from these remote mail clients I see one of two things: connection refused no route to host
These clients are internal and on the same subnet so I try telnetting directly to the mailservers and all accesses work just fine coming in direct like that. So I tried restarting keepalived. This managed to clear the access for port 25 and port 110 but not for port 143. Port 143 still won't connect. Nothing else seems to help until I reboot both director boxes and then and only then can the client regain access to port 143 for a few hours until the problem starts again. I looked through the howto's and the only thing I found that seems somewhat related is the discussion in section 28.14 Long sessions through LVS DR director terminated by icmp-host-prohibited (ICMP type 3 code 10). I don't know if I've bumped into this but I cannot figure out anything else that might be the cause.
