I'm upgrading, but I can't run the upgrade:
Error, can't open configuation file: "//usr/local/etc/perfparse.cfg"
I'm logged as root. The perfparse.cfg owner is root. What mistake am I
doing?

nagios 1.2
redhat 9

As you said below nagios remains running, bur stops performing checks.

[Wilson Pires Jr] 
Ok. The versions are above (nagios 1.2, rh9). I've used nagios-1-x-cvs
trying to correct the problem, but it persists.
If you can, I ask your tips since I don't know what HUP or SIGHUP exactly
does.
