The reason is that I run X windows with *MANY* windows. I called IBM, and got this answer: To look at the system configuration, become root and type: lsattr -E -l sys0 You will see that maxuproc is 40 (max 40 processes per user). AIX allows you to change that without rebuilding the kernel, or even rebooting. Just do: chdev -l sys0 -a maxuproc=80 And voila! you can now run 80 processes per user. If you start running low on paging space, send me email and I'll tell you how to increase it (again without rebuilding or rebooting).
