Yout might post the output of ssh -vvv host. And you might also look at the logs on the host. That error is pretty generic.

Re: sshd[27382]: fatal: Read from socket failed: Connection reset by peer ()

Mohd Rasidi Che Mat — Tue, 16 Jun 2009 01:16:36 GMT

is it safe to supress it? currently there is no impact on the server.

If it is not causing an issue, I might disregard it. You might look at /var/log/messages and /var/log/secure on es-prod01 for clues.
