Administrator

Sorry, can't imagine why anyone would want to configure a UNIX kernel for more 64,000 concurrent processes.

What you are basically saying is that an administrator
could do a 'ps -aux' command to look at the process table
and would see 64,000 processes!

With the inexpensive price of CPUs, memory, disks, etc.
this is simply not a practical way to set up any platform.

But,to answer your question, albeit indirectly, there are normally formulas for kernel parameters associated with the OS. You can't just 'increase processes' without lowering another value i.e. 'file descriptors' or perhaps other kernel parameters (don't have the formulas handy, sorry).

The README files in the kernel configuration directory tree should have the formulas. Could you post these formulas?

killall5

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME

       killall5 -- send a signal to all processes.

SYNOPSIS

       killall5 -signalnumber [-o omitpid[,omitpid..]]	[-o omitpid[,omitpid..]..]

DESCRIPTION

       killall5  is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so
       it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d
       directory.

OPTIONS

       -o omitpid
	      Tells killall5 to omit processes with that process id.

NOTES

       killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program.

EXIT STATUS

       The  program  return  zero  if  it  killed  processes.  It return 2 if no process were killed, and 1 if it was unable to find any processes
       (/proc/ is missing).

SEE ALSO

       halt(8), reboot(8), pidof(8)
