CentOS - Feb 2018 - pid_max

I have two systems both running CentOS 7.4

one shows pid_max as 32768
the other shows pid_max as 49152

Why might that be ? I would have thought they would be the same. I have not
changed them.

Thanks,

Jerry

Where does it come from, tuned profiles?

I think that max is calculated as a function of number of CPUs. Maybe
those two installations differ in that regard?

Hi Peter, Thanks... The machine with the higher PID number is a Xeon while
the other one is a i7.
So that could be why its different.

Thanks
