Perhaps this suggestion is applicable:
setup a cron job where the sshd server is restarted (once or several times
per day, or per week, etc).

At one time, I had a server on an ISP that, with time, became woefully
underpowered (the anti-spam/anti-virus program ate CPU power and RAM) to
the point that occasionally, and with more frequency (once a week?) sshd
would become unresponsive. This required that someone be at console to
restart sshd; or if the problem was not understandable, reboot the box.

Having sshd restarted in cron worked until we got a new, soopa-doopa box.
