To do a self-exec or self-restart of a process when it crosses the threshold memory limit, I use the value of virtual memory size field from /proc/$pid/stat file and do a self-exec.
According to man 5 proc
I just want to know, whether calculating vmsize of the process is the right way to identify total memory consumption of a process? Should resident set size be taken into account or per process swap usage?
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)
Hello all

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

I have a java process which is showing high virtual memory utilization in client server. But the same process is showing comparitively lesser virtual memory consumption.

plimit
plimit(1) User Commands plimit(1)NAME
plimit - get or set the resource limits of running processes
SYNOPSIS
plimit [-km] pid...
plimit {-cdfnstv} soft,hard... pid...
DESCRIPTION
If one or more of the cdfnstv options is specified, plimit sets the soft (current) limit and/or the hard (maximum) limit of the indicated
resource(s) in the processes identified by the process-ID list, pid. Otherwise plimit reports the resource limits of the processes identi-
fied by the process-ID list, pid.
Only the owner of a process or the super-user is permitted either to get or to set the resource limits of a process. Only the super-user
can increase the hard limit.
OPTIONS
The following options are supported:
-k On output, show file sizes in kilobytes (1024 bytes) rather than in 512-byte blocks.
-m On output, show file and memory sizes in megabytes (1024*1024 bytes).
The remainder of the options are used to change specified resource limits. They each accept an argument of the form:
soft,hard
where soft specifies the soft (current) limit and hard specifies the hard (maximum) limit. If the hard limit is not specified, the comma
may be omitted. If the soft limit is an empty string, only the hard limit is set. Each limit is either the literal string unlimited, or a
number, with an optional scaling factor, as follows:
nk n kilobytes
nm n megabytes (minutes for CPU time)
nh n hours (for CPU time only)
mm:ss minutes and seconds (for CPU time only)
The soft limit cannot exceed the hard limit.
-c soft,hard Set core file size limits (default unit is 512-byte blocks).
-d soft,hard Set data segment (heap) size limits (default unit is kilobytes).
-f soft,hard Set file size limits (default unit is 512-byte blocks).
-n soft,hard Set file descriptor limits (no default unit).
-s soft,hard Set stack segment size limits (default unit is kilobytes).
-t soft,hard Set CPU time limits (default unit is seconds).
-v soft,hard Set virtual memory size limits (default unit is kilobytes).
OPERANDS
The following operands are supported.
pid Process ID list.
EXIT STATUS
plimit returns the exit value zero on success, non-zero on failure (such as no such process, permission denied, or invalid option).
FILES
/proc/pid/* process information and control files
