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.
