ssh_exchange_identification: Connection closed by remote host
I'm randomly getting the following error on a server from various remote hosts: ssh_exchange_identification: Connection closed by remote host The server is running OpenSSH 4.5p1 w/GSSAPI Key Exchange patch. The hosts connecting to it should all be using OpenSSH 5.0p1 w/GSSAPI Key Exchange patch and using gssapi-keyex authentication. Normally, when I've seen this error, it means access to the SSH port is blocked by TCP wrappers or something like that, but I'm sure that's not the case here since /etc/hosts.allow and /etc/hosts.deny haven't changed for quite some time. Also, the failures are random from many different remote hosts and I can try a connection from a host right after it's failed and it will work. Under what other conditions might I get this error and how can I track down what's causing it?

I frequently see this error when / goes away, e.g. hdd failure.
