no job control in this shell as a warning return

A linux server of ours is returning warning:
System call sent warnings to stderr: bash: no job control in this shell
this is for: Total Processes otherwise the server is monitored correctly and not returning any errors. The server is running CentOS 5.10...where do I find out what is spitting that error message out? The box has been up 265 days, I was thinking a reboot might be the best way to start troubleshooting.

Are you using job control in the plugin script? (backgrounding, pausing processes, etc) If so, this is usually not allowed.

What does that call look like?

Why don't we go the route of, what plugin are you using that has this issue? Do you have a link, or can attach it here?

attached is the .cfg file that is read by nagios.
Looks like we are using:
Let me know if I should include anything else.
To me it looks like this call:
check_nrpe!check_local_procs!250!400!RSZDT
is the problem? mh419 is not having an issue, only the device mh409.

Can you post a copy of the check_local_procs plugin?

Code: Select all
# 'check_local_procs' command definition
define command{
command_name check_local_procs
command_line $USER1$/check_procs -w $ARG1$ -c $ARG2$ -s $ARG3$
}

This is most likely a problem with a configuration setting on the remote system. Do you have any particular security setup? selinux, disabletty in /etc/sudoers, etc?

Well, it was working ... and just started alerting.
selinux disabled
I see no reference to disabletty in the sudoers file either!

How about /sbin/nologin in /etc/passwd? (Though this should not matter)
What has changed since it was last working?
