Linux To Allow Adjusting pid_max Per PID Namespace - Helping Old Software

Sun, 01/19/2025 - 19:53
The pid_max tunable for the maximum number of process IDs allowed simultaneously was increased by default back in 2019 with systemd. But that increase breaks a long held assumption by some user-space software that pid_max or the process ID would not be greater than 65,535. To now better workaround such outdated user-space software, a set of patches for the Linux 6.14 kernel will allow adjusting the pid_max limit on a per PID namespace basis to help cope with such software hitting such artificial limits and without having to lower the overall system limit...
