Red Hat / Fedora :: System Is Eating More Memory And The Usage Is Keep On Increasing And At Particular Time
May 5, 2011
My server is keep on hanging So I have rebooted several times in the last couple of weeks, the system is eating more memory and the usage is keep on increasing and at particular time it became saturated and my server hungs. I could not find which process is eating more memory. I have used the below commands to check if any process is eating more memory but no luck. No such process are using high memory.
I'm running a recursive DNS server on Ubuntu Server 10.04 64bits and Bind 9.7.0-p1 and having issues with memory usage. The named process memory usage keeps increasing from about 500Mb to 4Gig inside of a couple of weeks. If I don't restart Bind in the mean time the swap fills and performance gets very bad.
Xorg takes 700+ mbs of ram, then in matter of hours it fills the swap and then system basically stops responding or whatever. And because its constantly allocating, it degrades perforamce horribly.Interesting thing is I never had this problem before, recently one of my ram modules broke (2+2 GB) and now I have only one, but it still doesnt explain the memory overuse. Windows 7 works perfectly fine.
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.
I use a Debian Squeeze system running off a flash drive, i.e. based on a custom Live image running in persistent mode. It runs great and I am grateful for the existence of Debian . However, I have a question. A lot of the machines I use this pen drive on are quite old, often with 512 MB RAM and old processors. I specifically built my system using XFCE and lightweight apps off an initial live image using the standard-x11 package list (basically just Xorg with drivers and the base system). At first things ran very well, blazing fast even on the oldest systems and could comfortably run Firefox along with LibreOffice side by side (I need LO as all of my colleagues use Word docs, often with track changes, which Abiword can't handle properly). However, over time, I've found that memory usage has risen, tot he point where Firefox is now automatically killed on the older systems every time I start LibreOffice.how does one figure out why memory usage is going up? I've checked for inessential services and turned them off with "insserv -r". I've used only lightweight apps, as mentioned before. Are there other general tips on reducing memory usage?
in this example, my memory 993.4 MiB memory is said to have 575.9 MiB of it used and 163.4MiB of my 2.8 GiB swap memory used. but in my processes tab, the most memory hogging program is 98.3 MiB, and Pidgin, 25.9 MiB, and 18.9 MiB, 14.9, 6.2,6.1,5.2,3.4,3.3,1.8,1.8,1.7, etc. I'm certain these don't add up to 575.9 MiB so where is all this extra memory usage coming from?
I am sure that all of us know the result of top command in linux. i want to get the value that the top command return as CPU usage, memory usage. so how do i do(programming relation)?
If I have a centos linux server, how can I stop a user on the server from eating all the memory and swap space memory, maybe due to a poorly written script, infinite loop etc?
Basically I have a machine with 16GB of RAM and have just discovered that using all of it can crash the whole system over one process. How could I run a process on the system in such a way that if more than 90% of system memory is used, the process immediately crashes?
I have installed Debian Lenny today from netinst cd. It all went good, hen I installed some basic utilities, daemons and libraries like dbus, hal, libgtk2.0, libasound2, alsa-utils, htop (for checking system load). Then I installed X.org with commandaptitude install -R xserver-xorg xserver-xorg-input-mouse xserver-xorg-input-kbd xserver-xorg-video-intel xinit xterm twmI used -R to pull less dependencies. When I ran startx X Server started, and I got on twm. But when I checked on htop, my memory usage was 175MB, and before starting X Server it was only 25MB. Why is X Server using so much memory on Lenny? I also have Debian Sqeeze on a different partition, it uses so much memory with all gnome services running+ iceweasel and amsn.
Im using SUSE, i have 31GB of memory Mem: 31908592k total, 31429632k used, 478960k free, 12176k buffers. How do I find out what process are eating up all my memory.
I'm running several SHOUTcast server instances and a WowzaMediaServer instance on a CentOS machine. I'm experiencing a memory leak problem, but I can't figure out which processes are eating memory.
TOP command reports as follows:
[Code]...
Something misterious to me (I'm still a Linux newbie) is that TOP reports a total of 7.5GB used ram but very small percentage for single process (0-1%). Memory consumption starts at 1GB/8GB after reboot and in three days running gradually increases up to 8GB. I'm practising with Linux, but I still miss a lot to understand what's happening on my system. For instance, are there linux kernel logs saved somewhere that I can look at?
I was trying to get the status of memory usage and disk usage using sigar in windows and ubuntu. done this in windows by just copying the sigar library into jdk library. But i was unable to do so in ubuntu. I've copied the library to java-6-sun library but still can't run the program.
I'm running Ubuntu 9.10 (I know I'll upgrade this winter). I've started to notice that java is eating way more CPU time then it has any right to, even with a fresh reboot and Firefox closed. I have java version:
I'm trying to understand the performance of my machine and memory usage just isn't adding up. When I run top it will typically show 301M of 308M used but the total of everything in the RES column is no where near 300M and the total of %MEM column isn't more than 20-30%. So how do I figure out what is using all the memory? Then is there some way to control it to optimize performance?
Memory of my Linux database servce is all used up. I first noted that this morning and rebooted the box. 5 hours later, it saw used up again. I want to find out which process is responsible for using most of the memories. What Redhat Linux utility can list processes sorting by their memory usage, like the Windows task manager?free and vmstat - summary but not for each processtop appears to be infomative, but sum of non-zero %MEM never add upp to 100
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.
I am looking for free database that has low memory usage and innodb and memory like engins that has C API and support trigger and client/server support for using in embedded linux systems.
I got a legacy server, and through munin I notice that periodically commited memory keep on increasing. The chart looks like a spiky sine graph, but every cycle it increase both max and minimum. After few days it will go over my physical memory it will keep on growing until the machine crash... Usually I reset the memory by rebooting the machine which is not a solution at all. Is there any way to know what process(es) that took the committed memory? Is there any way to release the committed memory without rebooting the machine? Is there any way to cure my machine from this disease? as an information, I'm using CENTOS 5.5 i686, AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ this is what I get from /proc/meminfo
MemTotal: 3499776 kB CommitLimit: 10023760 kB
currently
Committed_AS: 3972804 kB which is bigger than my MemTotal
My manager has asked me to look at memory drop on system while I was doing test on Linux machine. there is a big dip in memory graph produced by another tool. I do not know which processes were responsible for those memory dips. Is there any way I can find memory utilization of process during last week?
I am running Fedora 15 along with Windows 7 on my Dell laptop. Yesterday, when I was trying to install TeX Live, it stopped in between saying that there is no space left in File System. Even though I have space in my hard drive volumes, space seems to be running out of my system partition which is only 9GB in size (I guess!).I am posting a few results that might help you guys. I have an unformatted 15GB partition. How can I add it to my system partition? And is my var folder too big (1.5GB)? If yes, how do I backup its contents and then delete them? Additionally, the File System shows a folder 'media' (89GB) which links the C: drive that contains Windows 7 and my personal files. Should it remain that way or should I separate it? If the latter, how? I just couldn't find any.
Code: #df -h Filesystem Size Used Avail Use% Mounted on
I upgraded from Fedora 13 to 14 over the network. Everything seems to have worked. The one problem after my install is that I have noticed that setroubleshootd consumes alot of memory.
[Code]
It doesn't take long for setroubleshootd to jump in memory usage. I can kill the process but it will start up again. I have tried disabling the service but it doesn't show up in /etc/init.d. # service setroubledshootd stop setroubledshootd: unrecognized service So I am not sure what I can do to resolve the issue with setroubleshootd besides killing it off every 15 minutes.
In our database, when checking the memory used using top command, we are always seeing 32 GB RAM utilized. We have set the sga_max_size to 8gb and PGA to 3 gb. We have tried shutting down oracle db and then the memory went down to 24GB when checked using top command. After cold reboot of the DB server, it gone down to 1.5 GB.
But once the users are started using after end of day, the memory again gone back to 32 GB.
I'll often run iceweasel for watching videos via flash (hulu, ....., et cetera) while working, in fedora I never noticed any performance problems, watching the video while using chrome for browsing, gedit for editing, et cetera, everything was responsive. Though, now on debian running iceweasel for the same purpose hogs memory and processor time, which slows down the responsiveness of the system as a whole, making it difficult to use other programs.I'm curious how I should go about troubleshooting this issue, and what diagnostics might help me find the solution.
I've come across a really strange issue with one of my RHEL servers. The "free" command shows that 7019 MB of memory are actually in use by my system, but when summing up the actual usage (or even virtual usage like the example below) it doesn't add up - the sum is far less than what is reported by "free":
I was browsing my folder with lots of images, after finished i close nautilus and i notice that my computer became slow, so i'll check it with system monitor and had found that nautilus are using almost 100mb of ram (opening 4 tabs). I'm not sure if this was normal or not because i try to reopen the same folder with pcmanfm and it only consumes less than 20mb of ram (opening 4 tabs). here's the screenshot from system monitor .
