And this is a simplified version of my Nagios check script, that checks user's threads (LWPs) and processes.
Does it run on AIX?
It can only report one user. If two or more users are above thresholds it reports the top user.

I need a mechanism to fork child processes and all child processes should connect to a server.but the number of child processes should be limited(for ex:50)
Here's my pseudo, but I cant figure out how to limit the child process number. Should I use a semaphore? or what?

Hi
Is there a way to count how many processes a script has started, count how many of these have finished, and make the script wait if their difference goes over a given threshold?

Hey I'm new in linux,

I have already tried this code:

Hi,
Is there a maximum number of processes kernel parameter in AIX.
Solaris has max_nprocs,
HP-UX has nproc,
I can only find max user process (maxuproc) for AIX.
Thanks,

Morning,
Somebody can tell me in AIX 6.1 what is the different between the maxuproc (lsattr -El sys0 | grep max) and the for a user.
Example:
Oracle is limited by :
#ulimit -u
processes(per user) unlimited
But lsattr -El sys0| grep maxuproc show me :
maxuproc 16384

// AIX 6.1 & Power 7 server
I have maxuproc set to 16384.
lsattr -El sys0 -a maxuproc
maxuproc 16384 Maximum number of PROCESSES allowed per user True
What is the maximum number of maxuproc we can go for?
If I increase maxuproc to the higher number, what would be ramifications?

Hi Guys,
I am running RHEL6 and now my processes reach maximum limit.
How do I increase the maxuproc value?
Can I increase the value without rebooting the server?
Thanks in advance...

fork
FORK(2) System Calls Manual FORK(2)NAME
fork - create a new process
SYNOPSIS
pid = fork()
int pid;
DESCRIPTION
Fork causes creation of a new process. The new process (child process) is an exact copy of the calling process except for the following:
The child process has a unique process ID.
The child process has a different parent process ID (i.e., the process ID of the parent process).
The child process has its own copy of the parent's descriptors. These descriptors reference the same underlying objects, so that, for
instance, file pointers in file objects are shared between the child and the parent, so that an lseek(2) on a descriptor in the child
process can affect a subsequent read or write by the parent. This descriptor copying is also used by the shell to establish standard
input and output for newly created processes as well as to set up pipes.
The child processes resource utilizations are set to 0; see setrlimit(2).
RETURN VALUE
Upon successful completion, fork returns a value of 0 to the child process and returns the process ID of the child process to the parent
process. Otherwise, a value of -1 is returned to the parent process, no child process is created, and the global variable errno is set to
indicate the error.
ERRORS
Fork will fail and no child process will be created if one or more of the following are true:
[EAGAIN] The system-imposed limit on the total number of processes under execution would be exceeded. This limit is configuration-
dependent.
[EAGAIN] The system-imposed limit MAXUPRC (<sys/param.h>) on the total number of processes under execution by a single user would be
exceeded.
[ENOMEM] There is insufficient swap space for the new process.
