These errors sometimes appear and giving in schedule an immediate check disappear.

What is the reason they go sometimes and not others?

It is possibly due to networking issues since with some of those checks you can schedule an immediate check and it returns a non critical plugin error. It sounds like these are NRPE checks, please take a look at:

Section III of the document linked above has a few possible solutions. . . .
1) Allowed hosts configuration.
2) SSL not compiled in to nrpe.
3) xinetd nrpe source limit.

The usual problem is cause number #1. Make sure that the remote system has the nagios server ip configured - either in /etc/xinetd.d/nrpe (if you are using xinetd) or /usr/local/nagios/etc/nrpe.cfg (if you are just using an int script).

How did you install nrpe? (repo/source/XI agent download)

Thank you very much abrist.
I modified the value in xinetd.d on linux machines.

How do I edit these values ​​in the HP-UX machine?
These machines have not xinetd.conf.

Thanks for your help.
regards

What method of installation was used for the HP-UX servers? (repo/source/agent package from xi)

Thank you very much for your reply.

With the solution in the file xinetd.conf, the error not appears.

Thanks for your time.

Glad to see it working. I am going to lock up this thread now, so feel free to open a new one if you have any questions in the future.
