i would say that these are the kernel values you are looking for:

Code:

root@jumpy # adb -P ">> " -k /dev/ksyms /dev/mem
physmem 1f014
>> pidmax /D
pidmax:
pidmax:         30000
>> max_nprocs /D
max_nprocs:
max_nprocs:     15882
>> maxuprc /D
maxuprc:
maxuprc:        15877
>>
root@jumpy # uname -a
SunOS jumpy 5.9 Generic_118558-11 sun4u sparc SUNW,UltraAX-i2
root@jumpy #

pidmax --> Specifies the value of the largest possible process ID.
default = 30.000; could be set from 266 to 999.999 (pidmax sets the value for the maxpid variable. Once maxpid is set, pidmax is ignored.)

max_nprocs --> Specifies the maximum number of processes that can be created on a system.
default = 10 + (16 x maxusers); 266 to value of maxpid. [where maxusers defines the number of logged in users the system could support.]

maxuprc --> Specifies the maximum number of processes that can be created on a system by any one user.
default = max_nprocs - reserved_procs; could be 1 to max_nprocs - reserved_procs [where reserved_procs specifies the number of system process slots to be reserved in the process table for processes with a UID of root (0).]

kmem

MEM(4)							     Linux Programmer's Manual							    MEM(4)

NAME

       mem, kmem, port - system memory, kernel memory and system ports

DESCRIPTION

       mem  is	a  character  device  file that is an image of the main memory of the computer.  It may be used, for example, to examine (and even
       patch) the system.

       Byte addresses in mem are interpreted as physical memory addresses.  References to nonexistent locations cause errors to be returned.

       Examining and patching is likely to lead to unexpected results when read-only or write-only bits are present.

       It is typically created by:

	      mknod -m 660 /dev/mem c 1 1
	      chown root:kmem /dev/mem

       The file kmem is the same as mem, except that the kernel virtual memory rather than physical memory is accessed.

       It is typically created by:

	      mknod -m 640 /dev/kmem c 1 2
	      chown root:kmem /dev/kmem

       port is similar to mem, but the I/O ports are accessed.

       It is typically created by:

	      mknod -m 660 /dev/port c 1 4
	      chown root:mem /dev/port

FILES

       /dev/mem
       /dev/kmem
       /dev/port
