configuration parameter needs to be logged when exceeded

maxuproc : specifies the maximum number of user processes allowed. When this number is exceeded some programs behave unpredictable and there is know way to know what the problem is since it is not logged (errpt nor syslog)

    This was delivered in AIX Version 7.2 Technology Level 5: 7200-05-01-2038

    The problem reported in this RFE is related to getrlimit(RLIMIT_NPROC) returning unlimited for the user max number of processes, but the system enforces the maxuproc limit, meaning fork() fails when the user exceeds maxuproc number of processes when it is not expected.

    Starting with AIX 7.2 TL 5, maxuproc will behave like a hard maximum for ulimit: If a process forks and maxuproc has been increased or decreased, then getrlimit(RLIMIT_NPROC) will show the maxuproc value as the maximum for the child process. An existing (or parent) process is not affected by changes to maxuproc. It's ulimit remains the value that was in effect at the time it was created.
