bigcouch log rotation doesn't work as expected

the bigcouch logs should get rotated every day, class site_couchdb::logrotate creates this file:

root@ant:/opt/bigcouch/var/log# cat /etc/logrotate.d/bigcouch 
/opt/bigcouch/var/log/*.log {
	rotate 7
	daily
	compress
	missingok
	notifempty
	copytruncate
}

however, the logs are not rotated every day:

root@ant:/opt/bigcouch/var/log# date
Wed Jan 15 14:57:11 UTC 2014

root@ant:/opt/bigcouch/var/log# ls -alh /opt/bigcouch/var/log/bigcouch.log
-rw-r--r-- 1 bigcouch root 140M Jan 15 14:57 /opt/bigcouch/var/log/bigcouch.log

root@ant:/opt/bigcouch/var/log# head -1 /opt/bigcouch/var/log/bigcouch.log

root@ant:/opt/bigcouch/var/log# logrotate -d /etc/logrotate.conf 
...
rotating pattern: /opt/bigcouch/var/log/*.log  after 1 days (7 rotations)
empty log files are not rotated, old logs are removed
considering log /opt/bigcouch/var/log/bigcouch.log
  log does not need rotating
