Hello,
I am trying to understand the VIRT field that shows in the TOP command output. I have a users application that appears to be leaking memory. I see that the field VIRT in the top output is showing 55.8g.
The question is where is that getting stored? The disk does not appear to have that much space used on it. An the system only has 24GB of ram. Is this a combination of RAM and DISK? Here is some examples.
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!
I work with HP-UX and I have to monitorize the use of virtual memory for different processes.
(java processes for Tibco Adapter) And if these processes exceed a limit send a message to the syslog.
I donīt know how to monitorize this...
Should I do a script? or use an aplication, for example... (3 Replies)
Hi,
Would any one be so kind to explain me :

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 All,
Does anyone know what the best commands in the UNIX command line are for obtaining this info:

So, I would ask you a piece of advice about which books or titles could give me comprehensive information about virtual memory in UNIX. Especially, I would found out that virtual address translation corresponds structures of kernel!

ps
PS(1) General Commands Manual PS(1)NAME
ps - process status
SYNOPSIS
ps [-alxU] [kernel mm fs]
OPTIONS -a Print all processes with controlling terminals
-l Give long listing
-x Include processes without a terminal
EXAMPLES
ps -axl # Print all processes and tasks in long format
DESCRIPTION
Ps prints the status of active processes. Normally only the caller's own processes are listed in short format (the PID, TTY, TIME and CMD
fields as explained below). The long listing contains:
F Kernel flags: 001: free slot 002: no memory map 004: sending; 010: receiving 020:
inform on pending signals 040: pending signals 100: being traced.
S State: R: runnable W: waiting (on a message) S: sleeping (i.e.,suspended on MM or FS) Z:
zombie T: stopped
UID, PID, PPID, PGRP The user, process, parent process and process group ID's.
SZ Size of the process in kilobytes.
RECV Process/task on which a receiving process is waiting or sleeping.
TTY Controlling tty for the process.
TIME Process' cumulative (user + system) execution time.
CMD Command line arguments of the process.
The files /dev/{mem,kmem} are used to read the system tables and command line arguments from. Terminal names in /dev are used to generate
the mnemonic names in the TTY column, so ps is independent of terminal naming conventions.
