the mod_ssl configuration keeps a log of the pages served on :

  /var/log/httpd/ssl_request_log

there is no entry on /etc/logrotate.d/apache for that file, so it could get
as big as allowed for the corresponding filesystem.

an entry should be added so it is cut and rotated as all the other apache
logs as shown :

/var/log/httpd/ssl_request_log {
 missingok
 postrotate
  /bin/kill -HUP `cat /var/run/httpd.pid 2>/dev/null` 2>/dev/null || true
 endscript
}
