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.
