similar to: CentOS 3.5 system hanging

I have many different centos machines that are hanging regulary. I believe this is due to something our application is doing - not a centos specific problem. When the machines hang, there is no access to the console or remote access(ssh, rsh, etc). Any tips on debugging this issue? It is becoming quite a show stopper as we migrate our product from Solaris to Linux. tia, FYI - The

I have a dell precision 380: http://catalog.us.dell.com/CS1/CS1Page2.aspx?br=6&c=us&cs=555&fm=11210&l=en&s=biz with an Intel Matrix Storage Manager ICH7R RAID Controller http://www.intel.com/support/chipsets/imsm/sb/cs-020663.htm I need to get CentOS 3 installed on this thing but can't due to the fact that the controller is not supported in 2.4 kernels. There is a patch

I have an rpm I've created that has a dependency on a library provided by a third party. This dependency is not specified anywhere in my spec file yet the package seems to know about when I run: # rpm -qip --requires MyPackage.rpm The third party rpm is installed and uninstalled via a vendor-supplied script so that they can prompt you to accept licenses and so on. Problem is, the vendor

Is there a package I can get that will graph system resources such as CPU and disk I/O to an html file or something? Matt

Given that I have a machine with possibly multiple disks, each of which is bootable(has an MBR).... Is there a command that will query the BIOS and tell me which disk is the default boot disk. BTW - this is x86. The goal is to remotely reboot the workstation into the desired disk(which contain different centos versions). tia, -Mark -- Mark Belanger LTX Corporation

Is there a list somewhere of available updates for a given CentOS release? Something like this: https://rhn.redhat.com/errata/rhel4ws-errata.html Ideally I would like a something like: Bug Description Link to update 1111 kernel blah,etc http://some.rpm.com/1111.rpm -Mark -- Mark Belanger LTX Corporation

I have a user that is running centos on many machines. At each machine, the users is logged into a common account that is located elsewhere on the network. Meaning that everyone is logged on as user_x and accessing the home directory via NFS. All users are running gnome. On some of the machines, the nautilus process is pegging the cpu. At this time, I have no strace or other info to

Hey, I am looking for healt monitoring software for my centos5.1 box. Nothing crazy (like nagios), just something that records memory/cpu usage every min to 5 mins. I added some vmware stuff and was looking to see when if swap gets used and cpu spikes. -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

I've create a script and associated links(via chkconfig). The script runs in the expected runlevels at boot time, but does not run at all during shutdown(halt, reboot, etc). I swear I've done this a million times. What am I overlooking? # cat /etc/issue CentOS release 3.5 (Final) Kernel \r on an \m # chkconfig --list chnghst chnghst 0:off 1:on 2:off 3:off 4:off

I see in CentOS 3.6 - the release notes state that it has "improved support for dual-core processors" I got that from http://www.redhat.com/docs/manuals/enterprise/RHEL-3-Manual/release-notes/as-x86/RELEASE-NOTES-U6-x86-en.html Where might I get more details about this improved support. Specifically I'd like to see if problems I'm having in 3.5 could be related to the kernel

Hello , After upgrading the system from CentOS 7.2.1511 to CenOS 7.3.1611 I see that the average processing time has increased from 5-7% to 12-15% (doubled). Not critical but it is not pleasant. Server as KVM with 5 virtual machines. Someone noticed something similar? If so, how to fix that? Thx.

Hi, I have a server running Centos 5.2 and am implementing a GIS mapserver app. I have some sample logs from another implementation that give me an idea of bandwidth requirements but I would like to check the cpu load. I can not be at the server during the test and am interested in knowing if there is logging of cpu load available. Anyone have experience with this? Recommendations? Dave --

Hi to all! We're using CentOS 5.5 64bits for our Plesk 11. This week we had the following problem 3 times... Suddenly, the server stops responding in all services (SSH, Apache, Postfix, ...) but ping works! After wait a few minutes (or 2 hours some times) the server continues unresponsive until we reboot. After reboot we search on /var/log/messages but cannot find useful information...

Ok, we used to get this occasionally on cluster nodes, and we just got it on a fileserver (very bad). The system is discovered to be unresponsive: it doesn't ping, and plugging a console in, you can see that it's not dead, but there nothing at all on the screen, nor does it respond to even <ctrl-alt-del>. The only answer is to power cycle it; it comes up fine. Nothing in

Folks I use "yum list installed" to determine if a package has been installed. In particular, I was interested in the "man" program, installed with the command "yum install man". In Centos6, if I look at the results, I see that "man" was installed. This is good. In Centos7, if I look at the results, I see that "man-db" was installed. This

I'm trying to resolve an issue where a back is taking a *long* time. The data's being pulled from a CentOS 6 box by a CentOS 7 box. I went to use netstat, and iostat and sar... and they're not there. Should I install sysstat, or are there replacement tools I'm expected to use? mark
