I don't use RedHat but I believe that version is quite old. If you're security
conscious you might want to make sure that there are no known vulnerabilities
in the versions of the software you're currently running.

Is that from your httpd / Apache log files? It means that something or someone
has signalled the server to stop and restart. If someone has reconfigured
Apache they would need to signal it this way to make it notice the changes to
the config file. Is there anyone else who is authorised to admin that machine?
As to the b0rken CGIs, perhaps a change was made to the config files ages ago
that would have affected them, but the server was never restarted; now that
someone has restarted it those changes have taken affect. Look at the mtimes
on the Apache configs; compare them with old backups.

Ditto -- syslogd writes that when it starts up (boot time), or when it is
signalled to reload. This may be being done automatically by your system
when it wants to rotate the log files (it needs to restart things which have
the log files open to stop them from writing to the old, rotated files).

Is the time on the syslogd and Apache messages the same? If so, is anything
set to run at this time from /etc/crontab, /var/spool/cron/crontabs/*,
/etc/cron.d/*, or wherever your crond stores its configs (check the docs on
your system to find out where these config files are, they may not be the
same as the ones I've mentioned)?

I've not had any noticeable problems with bind 8.x, so maybe it's time to
think about upgrading. 

CERT <URL:http://www.cert.org/> have some good guides on the sort of tedious
but necessary admin and management tasks you need to think about if you're
serious about security. You have to put up with a mild amount of officialese
in the writing, though. ;-)
