why are boot.log and boot.log.1 getting updated but no reboot has taken place

We're seeing the boot logs, snmpd being restarted, etc. but no reboot has taken place according to who -b and uptime. Is there some overriding weekly clean up process causing this? All I see in cron is /root/bin/

This sounds like the action of a subsystem called logrotate. Quite commonly, a logrotate script needs to stop a daemon while it moves the logfile out from under the daemon, and then restarts it. You can find the scripts that do this in /etc/logrotate.d

This is what cron is running BTW:
$ grep 'daily' /etc/crontab
02 4 * * * root run-parts /etc/cron.daily

$ cat /etc/cron.daily/logrotate

/usr/sbin/logrotate /etc/logrotate.conf
if [ $EXITVALUE != 0 ]; then
    /usr/bin/logger -t logrotate "ALERT exited abnormally with [$EXITVALUE]"
exit 0
