Description
On the ulimits page we recommend setting nproc to 64000.
But in the Production Checklist for Linux, we recommend setting kernel.pid_max to only 32768.
This is inconsistent with the ulimits recommendations (which have been generally accepted as good baseline values, to the point that 64000 is used in the default mongod init scripts these days), because setting nproc to 64000 is useless if the system can only have less than 64000 concurrently running pids.
Therefore, the Production Checklist should be updated to recommend a kernel.pid_max value of 64000.
