Nagios just stopped running

[Rimbert Rivera]

It looks like we are using performance data, but I was able to rename
the current one and nagios created a new one and continues working
without having to restart nagios.  I did the same with
host-perfdata.out.  We'll add this to our periodic maintenance
procedure.

To your service-perfdata.out. If you don't need any performance data,
you can switch perfmormance data logging of. Depending on your
performance command definition, you can simply delete it. I don't know,
if you have changed that command. Look into misccomands.cfg, there it is
located by standard.
