Log rotation

If Kannel is configured so that the bearerbox, wapbox and/or smsbox log to file each of these log files
will continue to grow unless administered in some way (this is especially true if access logs are created
and/or the log level is set to debug).
A typical way of administering log files is to 'rotate' the logs on a regular basis using a tool such as
logrotate. A sample logrotate script (to be added to /etc/logrotate.d) is shown below. In this example the
Kannel log files found in /var/log/kannel are rotated and compressed daily over 365 days. See the
documentation for logrotate for more details. Of particular note however is the postrotate command, this
killall -HUP issues a HUP command to each kannel box running. The HUP signal has the effect of
reopening the log file, without this command Kannel will continue to write to the rotated log file.
