Number of processes per user (MAXPROCUSER)

Specify the number of processes that a single UNIX user (UID) can have concurrently active.

The default MAXPROCUSER(25) should be sufficient.

Some daemons or users run without UID(0) and may create many address spaces. These can require individually specified limits. For a specific user who needs more, use the RACF ADDUSER or ALTUSER command to specify a higher PROCUSERMAX limit for that user only.

Note: A user with a UID of 0 (zero) is not limited by the MAXPROCUSER value, because a superuser may need to be able to log on and use kernel services to solve a problem.

To conform to the POSIX.1 standard, set MAXPROCUSER to at least 16. To conform to the FIPS 151-2 standard, set it to 25 or more .
