I was having problems with the same server locking up to the point I can't even get in via SSH.
investigate instead of band-aiding...
1) syslog to a remote host. remote syslogging rarely stops when the system is disk/iowait bound.
2) log diving. is there anything in the logs around the time of the incidents?
large emails(100MB+ body, not attachment) can freak out versions of spam assassin... server load would reach 300+ which timed out SSH connections. syslogs took time to wade through, but pinpointed the recurring issue.
