The /etc/logrotate.d/syslog causes sysklogd-1.3.33-8 being restarted
several times
Jun 24 04:02:03 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:03 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:04 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:04 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:05 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:05 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:06 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:07 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:08 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:11 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:12 cmpq syslogd 1.3-3: restart.
 Jun 24 04:02:13 cmpq syslogd 1.3-3: restart.

This is 
1) wrong. 
2) may cause a race to restart sysklog several times.

The right solution will be to use sharedscripts
/var/log/messages /var/log/secure /var/log/maillog /var/log/spooler
/var/log/boot.log /var/log/cron {
missingok
  notifempty
  sharedscripts
  postrotate
/bin/kill -HUP `cat /var/run/syslogd.pid 2>/dev/null` 2>/dev/null || true
    endscript
}

Most of packages (samba, exim and others already do this
for log rotation to avoid multiple -HUP)
