Missing "&" in the cron ?

[FeG]

I've just detected another problem connected with this:

The daily cronjob causes an error, sent to me by mail:

Quote:error: error running prerotate script for /var/log/proftpd/ftp_traff.log, leaving old log in place
run-parts: /etc/cron.daily/logrotate exited with return code 1

The log-rotation for ftp_traff.log is defined as follows:

Code:

/var/log/proftpd/ftp_traff.log {
  daily
  rotate 7
  missingok
  compress
  delaycompress
  prerotate
    /var/www/ispcp/engine/traffic/ispcp-vrl-traff > /var/log/ispcp/ispcp-vrl-traff.log
  endscript
  postrotate
    /usr/bin/killall -HUP syslogd
  endscript
}

So here is ispcp-vrl-traff also called without an & ..

Again my question: Is it normal that this script causes errors (i.e. if, as joximu said, a domain hadn't caused any traffic this day) or is there a problem with my logfiles?
