Virtual Size actually is swapped memory + non swapped memory (physical mem amount for executable code + for data)..
Additiniol your program can probability use libraries..for this kernel present shared librarys..And your program wants memory from SHR memory space..
So according to me you maybe can use pmap tool for threshold memory limit
Hi,
First of all I appreciate this group very much for its informative discussions and posts.
Here is my question.
I have one process whose virtual memory size increases linearly from 6MB to 12MB in 20 minutes. Does that mean my process has memory leaks?
In what cases does the... (4 Replies)

Hi,
Would any one be so kind to explain me :
are ulimits defined for each user seperately ? When ?
Specialy what is the impact of :
max locked memory
and
virtual memory
on performance of applications for a user.
Many thanks.
PS :
this is what I can see in MAN :

Hi,
I am looking to work on unix systems which include (hp-ux, ibm aix, solaris and linux). I want to get the total virtual address space of a process, the used virtual memory i am able to get without any problem. I have tried using getrlimit and getrlimit64, but that gives only ... (4 Replies)
Hi All,
Does anyone know what the best commands in the UNIX command line are for obtaining this info:
current CPU usage
memory usage
virtual memory usage
preferably with date and time parameters too?
thanks

I was running a program and it stopped and showed "Out of Memory!". at that time, the RAM used by this process is around 4G and the free memory size of the machine is around 30G. Does anybody know what maybe the reason? this program is written with Perl. the OS of the machine is Solaris U8. And I... (1 Reply)
Hi all,
Is there any command which shows the virtual memory usage of a particular process in HP-UX machine.
I have tried with ps, top but could not get what I want.
Kindly provide me a solution.
Thanks in Advance

_________________________________________________________________DESCRIPTION
These functions handle fork and exec operations. See files: nsd/exec.c, nsd/tclenv.c and nsthread/fork.c.
Ns_ExecArgblk(exec, dir, fdin, fdout, args, env)
Executes a command in a child process. Return process id of child process exec'ing the command or -1 on failure. Provides extended
error checking and error messages.
Ns_ExecArgv(exec, dir, fdin, fdout, argv, env)
Execute a command in a child process using fork(2) and execve(2), returns the process id of child process exec'ing the command or -1
on failure. The child sends an extended error message to the parent.
Ns_ExecProc(exec, argv)
Executes a command in a child process. Returns the process id of the child process exec'ing the command or -1 on failure. Simpli-
fies call to Ns_ExecArgv.
Ns_ExecProcess(exec, dir, fdin, fdout, args, env)
Executes a command in a child process. Returns the process id of the child process exec'ing the command or -1 on failure. Calls
Ns_ExecArgblk with same arguments.
Ns_Fork()
Posix style fork(), using fork1() on Solaris if needed. See fork(2) man page. Calls ns_fork.
Ns_GetEnviron()
Returns pointer to the environment vector.
Ns_WaitForProcess(pid, statusPtr)
Wait for child process. Returns NS_OK on success, or NS_ERROR on failure. *statusPtr is set to the exit code of the child process.
Ns_WaitProcess(pid)
Wait for child process. Calls Ns_WaitForProcess with NULL statusPtr. Returns NS_OK on success, or NS_ERROR on failure.
ns_fork()
Posix style fork(), using fork1() on Solaris if needed.
