Package: varnish
Version: 2.1.3-8
Severity: normal

When logrotate is executed, varnish is restarted two times.
The condition of this bug: varnish.log AND varnishncsa.log are presents.

root@varnish-test:~# cat /etc/logrotate.d/varnish
/var/log/varnish/varnish.log /var/log/varnish/varnishncsa.log {
  daily
  rotate 7
  missingok
  compress
  delaycompress
  missingok
  postrotate
    for service in varnishlog varnishncsa; do
      if /usr/bin/pgrep -P 1 $service >/dev/null; then
        /usr/sbin/invoke-rc.d $service reload > /dev/null
      fi
    done
  endscript
}

root@varnish-test:~# ls -lth /var/log/varnish/
total 0
-rw-r--r-- 1 root root 0 Jun  7 04:41 varnish.log
-rw-r--r-- 1 root root 0 Jun  7 04:41 varnishncsa.log

root@varnish-test:~# logrotate --force /etc/logrotate.conf

root@varnish-test:~# tail -n2 /var/log/syslog

In /etc/logrotate.d/varnish, the instruction sharedscripts permits to avoid this bug:

root@varnish-test:~# vim /etc/logrotate.d/varnish
/var/log/varnish/varnish.log /var/log/varnish/varnishncsa.log {
  daily
  rotate 7
  missingok
  compress
  delaycompress
  missingok
  #Avoid to reload two times varnish
  sharedscripts
  postrotate
    for service in varnishlog varnishncsa; do
      if /usr/bin/pgrep -P 1 $service >/dev/null; then
        /usr/sbin/invoke-rc.d $service reload > /dev/null
      fi
    done
  endscript
}
