Nagios/NRPE giving a "No output returned from plugin" error

Question

Hi,

Getting a "No output returned from plugin" error message from a Nagios/NRPE script

1) Running Nagios v3.2.3 and NRPE v2.12

2) The script:

• OK_STATE=0

  UNAME=/bin/uname -r

  echo "OK: Kernel Version=$UNAME"

  exit $OK_STATE

2) Command line results on the Nagios Server using NRPE

• Same OK results for both the root and nagios users:

[nagios@cmonmm03 libexec]$ ./check_nrpe -H dappsi01b.dev.screenscape.local -c check_kernel OK: Kernel Version=2.6.18-194.11.3.el5

When I run the check_kernel.sh script on the machine's local command line it works there to.

Help, any thoughts or known solution regarding this would be appreciated?

Thank you
