This is probably the best way to do it. Or you could run the shell 
script put together in a system cronjob by Bastien and then in the 
DXSpider crontab run the 'run_cmd("load/prefix")' command.

The point being that you don't need to restart the node. You can simply 
reload the prefix file from the command line.  You can run commands by 
dropping a file, containing one or more DXSpider cmds into the 
cmd_import directory rather than killing the node. Do something like:

echo "load/prefix" > /spider/cmd_import/reload_prefix

and the node will execute that command and then delete the file. If you 
want to a do a weekly shutdown you can do that in the DXSpider crontab. 
But Bastien's script could simply do:

echo "shutdown" > /spider/cmd_import/shutdown

Assuming that you are using a standard installation, then the node will 
shutdown and then restarted automatically by systemd or init.
