pid_max setting

This topic explains how to change pid_max to a supported value. The value of pid_max should be

pid_max = num-user-proc + 2**15 = num-user-proc + 32768

where num-user-proc is the size of memory in megabytes.

The minimum value for pid_max is 524288.

If your pid_max value is too low, the installer reports this problem and indicates the minimum value.

The installer automatically configures the correct setting if the default value does not meet system requirements. If an issue occurs when setting this value, or you use the --no-system-configuration argument to the installer and the current setting is incorrect, then the installer reports this as an issue.

All systems

To change the pid_max value:

# sysctl -w kernel.pid_max=524288
