    This error indicates a truncate of the nrpe data received. 

    If you have compiled using a higher payload limit, your best bet is
    to check in the Nagios forums. 

    We will be working with upstream Nagios to get a higher packet size
    patch merged upstream.

             You can update the
              packages with the ones built from source.

              You will need to update both the client and server nrpe
              packages with the modified payload limit to resolve this

              - nagios-plugins-nrpe

              - nrpe

              
              Have you done that?

                        value still the same issue...

                                     Looks like you
                                      are hitting the NRPE Payload
                                      issue. Standard NRPE packages from
                                      epel/fedora has 1024 bytes payload
                                      limit. We have to increment this
                                      to 8192 to fix this. You can see
