CRITICAL - Plugin timed out while executing system call

[isthisyournacho]

One of my servers suddenly started complaining of this error at 4am this morning. The server has barely any load, and the services that are failing are check_remote_load, check_remote_disk, check_remote_swap, and check_remote_procs. They have been working for quite some time, and now I get: CRITICAL - Plugin timed out while executing system call

I can run the command manually on the server itself. I forgot to mention - one server connects to another server to run these commands, and I have about 5 servers being checked, only this one has the problem.

Here's a snippit of one of my config files:


# Define a host for the local machine

define host{
use linux-server ; Name of host template$
; This host definition $
; in (or inherited by) $
host_name Dev11
alias Dev11

}

#define service{

define service{
