title: 'Configure maximum number of process identifiers'
description: '{{{ describe_sysctl_option_value(sysctl="kernel.pid_max", value="65536") }}}'
rationale: |-
The <tt>kernel.pid_max</tt> parameter configures upper limit on process
identifiers (PID). If this number is not high enough, it might happen that
forking of new processes is not possible, because all available PIDs are
exhausted. Increasing this number enhances availability.
