If this is the wrong mailing list (though I doubt it is). Could someone please direct me to the right one? Should this question be directed to LKML instead?

Is there a way I can prevent processes from taking up all the ram then swap until the box crashes/freezes? I'm using IEs4Linux and the wineserver seems to start taking up RAM until my box dies, it happens slowly. I am able to kill the sucker now, but I'd like to not have to worry about that. sar -r 01:00:01 PM kbmemfree kbmemused %memused kbbuffers kbcached kbswpfree kbswpused

Hello all. I have a centos 4.4 box (2.6.9-42.0.10.ELsmp) with 7gig of ram that doesn't seem to be using swap (also 7gig now). I say "seem" because I've noticed ram utilization run around 95% (with oracle and friends running) and then firing up a couple apps to use that last 5% will stop the machine dead in it's tracks. I ran across some reading[0] about

We have DELL R900 server with 128GB RAM (CENTOS 5.5)in it. This server only have one application running and few people use it.

Hi people I will like to ask for the permission to rewrite the current FreeNX article. The current article is lacking in the information on how to add accounts to the nxserver on centos. I think it will be very difficult for linux newbies to understand how to read that article. I am a newbie too so I can understand the frustration when you can't find an appropriate HowTo article.

Hi all, Marking Wiki pages/howtos by CentOS version was discussed a while ago. How about using something like the attached MoinMoin (plugin) macro? It adds a macro named 'CentOSVersion' that could mark the page at the beginning of an howto in a uniform manner: [[CentOSVersion(4,5)]] This will draw a little table of the following form: --------------------------- | CentOS version: | 4 |

Hello, Over the weekend, I upgraded one of my servers that runs mysql and pdns to 5.3. Previous to the update I have not had an issue form this server. But since, I have had mysql die multiple times from oom-killer. $ uname -a Linux rack2a 2.6.18-128.1.6.el5 #1 SMP Wed Apr 1 09:10:25 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux Unfortunately, the server has been rebooted by others before I have been

hi guys, just spent 20 minutes looking through the forums on the website, and it seems people are posting howtos and walkthoughs there. whats the general feeling ? is it worth getting in touch with the authors and seeing if they would like to maintain them on the wiki instead ? I know some of them are really mad and we wont / dont want to highlight them too much ( like, gnome-2.16 hacked

Hello, Is there some document about ext3 performance tuning and choosing the right type and size of journal? Except RedHat's white paper. From what I read I understood that for typical operations data=ordered is prefered. For the cases when there are many writes not appending to files data=journal is the choice. And if I want to get the most performance or in case where program is doing

Hi all, This is my first post to the list, I hope someone out there can help! I am running xen 3.0.3, with CentOS 5.2 based Dom0 (kernel-xen-2.6.18-92.1.22.el5) Recently I have noticed some complete system lockups on a few different servers. Neither Dom0 or any of the guests respond to pings, connecting a keyboard and monitor to the system only shows a blank screen. Nothing is written to logs

We use single queue even if multiqueue is enabled and let admin to enable it through ethtool later. This is used to avoid possible regression (small packet TCP stream transmission). But looks like an overkill since: - single queue user can disable multiqueue when launching qemu - brings extra troubles for the management since it needs extra admin tool in guest to enable multiqueue - multiqueue

All, just having spotted the backport of Linux commit 03bbcb2e I notice a certain discrepancy with the Xen commit having the same purpose as well as with the actual specification updates: The Linux solution keys off of device IDs 3403 and 3406, as listed in the specification update, but this way fails to cover the X58 chipset, which has - under different numbers (62 and 69) - the same errata

Commit 4490001029012539937ff02778fe6180613fa949 ("virtio-net: enable multiqueue by default") blindly set the affinity instead of queues during probe which can cause a mismatch of #queues between guest and host. This patch fixes it by setting queues. Reported-by: Theodore Ts'o <tytso at mit.edu> Tested-by: Theodore Ts'o <tytso at mit.edu> Cc: Neil Horman <nhorman
