In system monitor, there are numerous processes. Some such as metacity and nautilus are using 12-21 mb memory. Since my server is a 512 mb computer, which services or processes can I safely remove or end ?

View 9 Replies View RelatedI have a home server set up with samba, proftp, and the torrentflux webUI via apache and mysql. To the best of my ability, I have stripped the system of any unnecessary software. After a fresh reboot the system uses around 250 mb of memory, which to me still seems like a lot, and after it has been on for a few hours with torrents downloading, the memory usage will steadily climb to and stay at 2 gb! Using top shows that the processes using the most memory are python, mysqld, and apache2. What the heck is going on?

View 2 Replies View RelatedChkconfig is a utility to update and query runlevel information for system services. Chkconfig manipulates the numerous symbolic links in /etc/init.d/, to relieve system administrators of some of the drudgery of manually editing the symbolic links.
In Debian, there are several tools with similar functionality, but users coming from other Linux distributions will find the tools in this package more familiar.
Go to Terminal and open it and type the command "chkconfig' press enter. code...
after installing just type "chkconfig"
you can see list of service which one is off or on in your system code...
How can Vsftpd services & Xinetd.d services can be differentiated?

I have a server running samba process and there are about 70 samba users connected at a time. The system has 4Gb of memory and it seems each samba process is utilizing only 3352Kb of memory.
When I run the command
pmap -d (pid of samba)
It gives as:
b7ffa000 4 rw-s- 0000000000000000 0fd:00003 messages.tdb
bfe46000 1768 rw--- 00000000bfe46000 000:00000 [ stack ]
ffffe000 4 r-x-- 0000000000000000 000:00000 [ anon ]
mapped: 33384K writeable/private: 3352K shared: 20504K
But when I run the top command, it results as below:
Tasks: 163 total, 1 running, 162 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.9% us, 4.9% sy, 0.0% ni, 93.3% id, 0.8% wa, 0.2% hi, 0.0% si
Mem: 3895444k total, 3163192k used, 732252k free, 352344k buffers
Swap: 2097144k total, 208k used, 2096936k free, 2487636k cached
Why could the system be utilizing such high memory? By the way, the server is not running other processes. The samba version running in it is 3.0.33-0.17.
The more context the better. So far it does not look like it has anything to do with memory.

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?

I went to Dolphin -> Settings -> Configure Dolphin -> Services -> Download New Services and from there I installed KDE CDEmu Emulator and MountISO. But neither of them is showing up in actual context menu. Neither in Dolphin -> Settings -> Configure Dolphin -> Services for that matter. I tried to install them as normal user and as a root. I went to have a peak in /usr/share/kde4/services/ServiceMenus/ but they aren't there as well... It's just me or lots of things seems to be not quite working in 11.3?

View 4 Replies View RelatedAfter a recent update of fedora 15 (2 days ago) I lost my networkmanager icon in top panel completely. Then I check network manager version & found it's version 0.8.0.9997-5.git20110702. After this update I can't connect to internet by any means either via wired or wireless connection. When I try to open Network option from system settings it giving me an error: System network services are not compatible with this version.
I also try to open network-connection-editor by pressing Alt+F2 & typing:
nm-connection-editor
But it not works as well, I can't see any existing network connection there, moreover I can't even manually add any type of network connection there including mobile broadband! Then I do some googling from my windows machine & found this thread- [URL]. According to this thread I try to do downgrading of following 3 packages-
Code:
networkmanager
networkmanager-glib
networkmanager-gnome
But I can't downgrade via yumex as there's no internt connection in fedora. so i do a trick of myself. yumex suggests me to downgrade them to previous version 0.8.0.999-2.git20110509
so i manually download those 3 packages from my windows machine & copy them to /var/cache/yum/... folder. After that I do downgrading via yumex. But even after downgrading problem isn't solved. Same things happening still. No networkmanager icon in top panel & no internet
at present, there's no internet connection in my fedora 15 machine & I'm writing this post from my windows machine.
Moreover when I give this command in terminal:
Code:
sudo service network start
it giving me FAILED status.
I've been looking at possible options - I might install new from the CD if I have to. But before I do that, I'm wondering if there's anything I can do to restore the system to the way it would have been if I'd actually done a clean install - but to leave /home intact and perhaps the application also. (I haven't installed that many). I'm running 9.10, upgraded from 8.04>8.10>9.04 - it's working but There are some issues I can't seem to resolve such as stuttering audio.

View 1 Replies View RelatedSince one of the recent updates, I cannot close the System Monitor anymore. Opening it, no problem. All processes are listed just fine and I can force close anything that gives me trouble but... When I want to close System Monitor again, nothing. Qtrl + Q, the X close button at the top right, Alt + F4... all do nothing. And although each time I see some disk activity, there is nothing in the logs.
Another thing I notice is that both dbus-daemon and gnome-system-monitor use about 40% CPU time each, taking the system to 100% CPU usage all the time.Luckily, I have System Monitor open so I can select the process gnome-system-monitor from the list and hit Terminate Process. I did not find anything about it in these forums. Anyone noticed this too or am I the only one?

This is my first post in these forums. I'm still quite new to Linux (using Mint 9) so please bear with my not-very-articulate question(s)When I boot up and open up a tty terminal I get a message saying "Memory corruption detected in low memory." I've done an extensive google search about the issue and it seems not uncommon. I ran a memtest with no errors returned, so I'm sure that there's nothing really wrong with the memory; apparently it's a bug in the kernel that's causing this.
