General :: Ubuntu - Memory Full, Process Memory Usage Doesn't Add Up In Top?

Mar 18, 2011

I have a computer with 16GB of ram. At the moment, top shows all the RAM is taken, (NOT by cache), but the RAM used by the various processes is very far from 16GB.I have seen this problem several times, but I don't understand what is happening.My only remedy so far has been to reboot the machine.

CentOS 5 :: Throttling Process Resource Consumption?

Mar 2, 2009

Is there a way of throttling a process resources, something akin to limits but for processes not users?ie I want processX to be restricted in the amount of memory it can consume. For process cpu I guess I can simply nice the process, but total memory consumption is my primary concern.

Ubuntu :: Memory Leak / Some Process Eating All Memory

Jan 29, 2011

I have had a fresh install of Ubuntu 9.10 and installed some software after that.Since third some, some process is eating half of my memory.I have checked processes running in system manager but everything is normal.Maximum is consumed by compiz which is about 26 mb, seems very normal.I did restarted my computer several times, and in the start for 5 mins, its fine after that again my cpu fans runs at very fast speed and my one cpu is used up 95 % (I have dual core).Please help me out, this invisible thing is driving me crazy.I am attaching my htop screen shot (sorted by cpu %), now the cpu is not used by completely but fan is still struggling hard and fast.

General :: Force A Process To Run In Virtual Memory?

Dec 9, 2010

I am running a series of tests for an implementation of a remote pager that sends page faults to other computers in a network. Long story short, I was wondering if there is an easy way to force a process to use virtual memory as oppose to physical RAM so that I can better measure the performance of my implementation against how the system would perform while swapping to the hard drive.

General :: Memory - Preventing A Process Being Swapped Out?

Aug 30, 2011

Does anyone know of a linux utility which will prevent all memory in a forked process from being swapped out to disk? I've seen the 'mlockall' call, but hacking the app sounds like overkill.My reason for needing this is that I'm running Windows XP under VirtualBox on my linux netbook, and I'm concerned there are basically two levels of swapping going on, which on a single dinky netbook hard disk isn't

General :: Calculating Process Memory Usage?

May 13, 2010

What originally seemed like an easy thing to calculate has given me a big headache. Perhaps someone can help me with my issue. I am trying to find, in particular, how much memory certain application processes are taking. The process always is the same name, main_server, but with an argument to tell it what to do when running as a daemon.

When running the following command against all "main_server" processes, it produces a result in megabytes based on the output of the rss field in 'ps'.

for ea in
`ps -e -orss=,args= |
sort -b -k1,1n |
grep main_server |
grep -v "grep main_server" |


Currently I am left scratching my head. For capacity planning purposes, it would be nice to know how many more 'main_server' processes could run on the system without causing it to swap. Knowing the buffer and cache usage will go down as running processes demand more memory, I prefer to look at the free memory excluding cache and buffers. However, since 'ps' is reporting the processes are using more memory than free reports is in use without those things, I have no way to know how many more processes the system can support. I played around with different fields in 'ps', such as vsize, size, etc, but with no luck in matching up any numbers.

General :: Testing - Stop OS From Allocating More Memory To A Process

Dec 2, 2010

I want to test that a process properly kills itself and restarts when it can't allocate needed memory. One idea I had was to start other memory-consuming processes and hope that OOM killer kills the process being tested, but 1) this isn't quite the same; 2) it may kill other processes instead; 3) since this is an embedded system, I don't have any programs available except for the system under test and BusyBox.Is there a more direct way to ensure that Linux won't allocate memory to a process?

General :: Explicitly Swap Out Main Memory Of A Suspended Process?

Apr 7, 2010

I run a memory-hungry process (mkcromfs) which consumes more memory than I have physical memory on my latop, so it is paging and swappin and thrashing all the time and loadavg is about 2 (compcache is already in use with usual swap partition as well), but slowly moving forward (Although I afraid it will finally try to allocate >2GB and crash draining 2 days of thrashing).

When I want to use the laptop for something else, I stop the process, start X server, firefox and other programs. The problem is that when I start Firefox the loadavg jumps to 10 and the system becomes almost unresponsive at all (long time to turn on/off caps lock, slow mouse cursor position updates, slow switching from X server to Linux console, slow login).

The stopped mkcromfs still holds a lot of memory (464.8 MiB and slowly falling) and moves it to swap only when more memory is needed for some other program, which results in a great slowdown.

How to tell the Linux to swap out this process entirely (e.g. I'm not intending to resume it in short term), possibly waking from swap other data? Also it will be useful to be able to specify the exact swap device to swap the given process out (for example, mkcromfs's memory is useless in ramzswap).

Update: Now I just write a 400-600M of data from /dev/erandom to tmpfs and it makes mkcromfs to shrink. Is there more proper way?

General :: Java Process Without Memory Detail In Proc File System?

May 13, 2010

To get the kernel messages of new java process, i refer the details from /proc/<java pid>/stat and /proc/<java pid>/statm files. For some java processes, I didn't find any details in the /proc/<java pid>/statm file. It has only 7 number of 0s. But /proc/<java pid>/stat file has the details. And also this kind of process will have the life time of nearly 1 minute.

Kernel version using: Linux-2.6.18-8.1.8.el5 Is there any possibility of java process without the memory details in the /proc/<java pid>/statm file? If it is possible, how to know the memory related details of that processes?

General :: Child Processes Of A Parent Process Occupying Socket Memory?

Jul 22, 2010

I am facing an issue where the process starts hanging. When I closely look at the logs I come to know that some of the child processes that are forked by the parent process are not finished.

1) Is it possible that the child processes that are not finished occupy the socket memory of the parent process and ultimately a point is reached where no socket memory is available to fork new child processes.

2) What is the standard limit of socket memory in linux?

3) What is the fate of such child processes (as I have mentioned above)?

4) How to debug such cases so that the exact problematic area is identified?

I need to process billions of small files using bash shell commands with limited memory size (256MB). If any of those files contain certain "keywords", the file will be removed. I tried with command:

find . -type f -exec grep -i -l -H "keyword" '{}' + | xargs rm -rf

where all files are located within the current directory. But the command above failed in "out of memory".

Software :: How To Get Size Of Memory Used By Each Process?

Jul 25, 2009

I need to know, what process for what purpose is using memory in my machine. ps utility with various options seems to give not exactly what i want, i.e. if i sum all the values like RSS, VSZ or some other values related to memory usage, the sum is not equal (even approximately) to what i get using free|grep "buffers/cache".
How can i get this information? Even better, i would like to see contribution of every process, ramdisk, etc. to memory usage.

General :: Unable To Model The Power Consumption Of Various Components

Aug 3, 2011

I am working on a traffic surveillance project which performs various image processing tasks with a number of visual sensors and a computing platform. My basic task in the project is the power optimization/management. I am using a ZOTAC-IONITX computing platform (Intel ATOM CPU + NVIDIA ION GPU). The problems that I am currently facing are:

I am unable to model the power consumption of various components e.g., processor, GPU, hard drive, memory etc, since there seems to be no way to measure the power consumption of individual system components. Since I don't have a power consumption model, I cannot come up with a power optimization algorithm. I am currently working on Linux. Is there any way to measure/model the power consumption of individual system component?

I have already checked powertop. It doesn't tells the power (watts) consumed by a component (e.g., microprocessor). It just gives information about the power state the processor is in (However there is no way to change the power state by the user) and the processors that cause processor to wakeup.
