    Hi

    Hope somebody can help me:)

    We specify the rotation of the logfile maillog as follows:

    /var/log/maillog {
        rotate 7
        daily
        compress
        postrotate
               /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2>
    /dev/null || true
        endscript
    }

    For some reason the command doesn't succeed, i.e. the signal never reaches
    the syslog daemon.
    Consequently, syslogd will continue to write to a INODE that no longer has a
    file pointer
    effectively resulting is log data being lost.

    However, if the command is modified to:

    sleep 1; /bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null` 2> /dev/null
    || true

    the problem disappears.

    The easiest way to test this is to do the following commands when
    configurating
    the logfile /var/log/maillog as given above:

    #/usr/sbin/logrotate -f /etc/logrotate.conf
    #ls -l /var/log/maillog

    Note that the size is 0

    #logger -p mail.info -t info TESTING
    #ls -l /var/log/maillog

    Note that the size is still 0

    #/bin/kill -HUP `cat /var/run/syslogd.pid 2> /dev/null`
    #logger -p mail.info -t info TESTING
    #ls -l /var/log/maillog

    Note that the size no longer is 0

    Thanks /Mattias
