Problem: my server eats up all the memory in the box after a few days. My guess is it has something to do with these processes:
[Code]...
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.

View 4 Replies View RelatedI 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.

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?
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 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.

We had servers that worked fine for years. After updated them to the latest version of CentOS (5.2 with latest updates), they keeps on hanging when being scanned by PCI Verdors (a Credit Card security standard). Basically, the scan causes httpd process to eat up all memory, and the server becomes unresponsive. Normal operations resume after the scan stops for 5, 10 minutes. Output from top looks like the following:
Mem: 1018988k total, 1007168k used, 11820k free, 432k buffers
Swap: 2096440k total, 2096440k used, 0k free, 4528k cached

I am running SuSE 11.3 ( 2.6.34.7-0.7-desktop) on a Dell Laptop I am using an external NAS (QNAP-809pro) that connects to the laptop via iSCSI When my laptop boots I get an error that stops the boot process and gives me the filesystem repair terminal: ther I have to comment out the iSCSI lines from /etc/fstab and reboot normally. This is my fstab with commented-out iscsi mount lines

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.
View 1 Replies View RelatedThe first server I installed installed fine. The second server, installed with the same config, went to "kernel panic not syncing no init found try passing init= option in kernel" error. I tried reinstalling but it keeps going to that error after install reboot. The storage is ISCSI connected via Intel Server Adapter, which allows it to boot from ISCSI. Not sure if that's the cause for the problem, but the first server is connected to the same ISCSI and installed just fine.
Is there a way that I can make sure ISCSI module installs during installation? Although I think it is installed since it's able to copy the files and setup /dev/sda. I just wana make sure that it installs during setup.
I have never done this before but stood up a new Debian (testing) x64 system. It only has 146GB available for RAID1 so I created a 500GB iSCSI LUN on my NAS device on the network and am really confused how I can attach my Debian to the iSCSI LUN I created. Right now the OS is installed all locally on the machine but I would like the iSCSI LUN to be the /home directory for mail storage. Is this possible or do I need to mount the LUN to a newly created folder / mount point that is locally attached?

I've been trying to figure out how to set up a partition on my CentOS serve r as an iscsi target, so I can access it from another CentOS client.I've been reading the manuals and various pages on the web, and nothing is very clear.

I built a CentOS 5 Linux cluster with GFS storage using local RAID volume and share it with gnbd_export/import on two web-servers. Now I need to expand that storage to another servers local volume. I saw the picture in the manual, but I don`t know, how can I create that scheme.
I can use gnbd_export on the second server and gnbd_import on the first. In that case I will have two volumes on the first storage and I can expand volume group, logical volume, etc on it.
What is the correct way to allow two servers to use the same file system on a SAN using iSCSI?Is it GFS on the two servers?
View 3 Replies View RelatedI have a server wich is connected to an iSCSI storage and gets harddisks from this storage. Sometimes I have to add new disks to this server. Everytime I add a disk and make an /etc/init.d/iscsi restart on the server the disks don't have the same device name as before the iscsi restart.
It should be possible to gave the disks persistent names using udev rules. Now I tried to create different rules in "/etc/udev/rules.d/99-static-iscsi-names.rules" e.g.
# /dev/sdc
KERNEL=="sd*", BUS=="scsi", PROGRAM=="/sbin/scsi_id -g -s %p",RESULT=="360a98000503355344c4a576864467877" NAME=="sdc%n"
In "/etc/rc.local" I added "/sbin/start_udev" and in "/etc/scsi_id.config" I added the line "vendor="NETAPP",model="LUN",options=-g"

I'm trying to configure an ISCSI/DRBD high-availability cluster and I'd like to know what is the best option between OpenAIS and Heartbeat. I've seen they both are included in Centos Repos, yet OpenAIS requires installing 2 addition repos to install Pacemaker (EPEL and Clusterlab repos).
View 1 Replies View RelatedWe have a Centos 5.6 server mounting two iSCSI volumes from an HP P2000 storage array. Multipathd is also running, and this has been working well for the few months we have been using it. The two volumes presented to the server were created in LVM, and worked without problem.We had a requirement to reboot the server, and now the iSCSI volumes will no longer mount. From what I can tell, the iSCSI connection is working ok, as I can see the correct sessions, and if I run 'fdisk -l' I can see the iSCSI block devices, but the O/S isn't seeing the filesystems. Any LVM command does not show the volumes at all, and 'vgchange -a y' only lists the local boot volume, not the iSCSI volumes. My concern is that, the output of 'fdisk -l' says 'Disk /dev/xxx doesn't contain a valid partition table' for all the iSCSI devices. Research shows that performing the vgchange -a y command should automatically mount any VG's that aren't showing, but it doesn't work.
There's a lot of data on these iSCSI volumes, and I'm no LVM expert. I've read that some have had problems where LVM starts before iSCSI and things get a bit messed up, but I don't know if this is the case here (I can't tell), but if there's a way of switching this round that might help, I'm prepared to give it a go.There was absolutely no indication there were any problems with these volumes, so corruption is highly unlikely.
I need a command that can get the memory consumption of a process called "job_runner_o".
