The New Relic Infrastructure agent, by default, runs in a single operating system thread. This may mean that, especially in Windows environments, the process scheduler gives it little chance to get CPU time when the system is overloaded.
The max_procs: -1 configuration option removes this limitation and allows the agent to use one thread per CPU core (as maximum).
