Doesn't sound promising. What's making it harder to diagnose is that there aren't any messages left anywhere but the client. According to sshd_config(5) the default LogLevel is INFO which should be enough to show up connection timeouts? Mind you, it's interesting that there isn't anything logged at all for the dropped connections, would've hoped that that might have rated an INFO level message of iteslf? (I do see messages from sshd in /var/log/messages - all failed logins). There aren't any messages relating to the network interface either, that I can see. Chuck suggested in another message to check the interface for errors. I can't see anything that looks untoward, maybe someone with a better understanding could cast their trained eye over my netstat output? (See ovirt@dyndns.uus/sysinfo/netstat.php?opts=[is] - replace the 'at' with a period and the double-u with a dubyah, use either i or s as the argument, defaults to 'i').
