[syslog-ng]Logrotate problems

[Simeon Johnston]

I am trying to rotate the logs but am having problems with logrotate.
This may not be a problem with syslog-ng.
This is the command used.

/var/log/logfile {
    postrotate
        /usr/bin/killall -HUP `cat /var/run/syslog-ng.pid`
    endscript
}

The problem with this is that the syslog-ng.pid file seems to be
generated in whatever directory you started syslog-ng from instead of
/var/run/*.  Is this a configuration problem of the system?  If a system
problem how do I go about fixing it ( if this is not too far off topic
)?  Is there a simpler way to send an HUP signal?

I am using Redhat-6.2 on an ALPHA with syslog-ng 1.4.11.

Thanks,
