apt-get upgradetold me that packages linux-headers-server linux-image-server were kept back, and thus this answer lead me to run apt-get install linux-headers-server linux-image-server. However, the command outputs the following: Reading package lists… Done Building dependency tree Reading state information… Done linux-headers-server is already the newest version. linux-image-server is already the newest version. You might want to run `apt-get -f install’ to correct these: The following packages have unmet dependencies: linux-image-server: Depends: linux-image-2.6.32-37-server but it is not [...]Continue Reading »

UPDATE: I updated the title of the message, because I’ve recently seen more of these problems with this exact time amount of 17163091968s. This should help people investigating the symptoms to find this page. See my (self-)accepted answer below. I have a bunch of 64-bit Ubuntu 10.04 LTS VM’s in a VMware vSphere datacenter. VMware tools is installed (vSphere Client says “OK”). I’ve seen some of the VM’s hang a few times with the following [...]Continue Reading »
I have a problem on Ubuntu 10.04.3 LTS x64 with sysctl net.ipv4.netfilter.ip_conntrack_max . If I run this command on shell, I get back an error: error: net.ipv4.netfilter.ip_conntrack_max” is an unknown key. It occurred on 2 of our machines after a reboot. The sysctl value net.ipv4.netfilter.ip_conntrack_count and all other conntrack-entries are also affected. This is really problematic because we have a very high load / traffic system and I have written a Nagios script which check [...]Continue Reading »

I troubleshooted the root cause to be the kernel update, here are the minimum steps to reproduce the problem: Launch a new RHEL 6.1 instance Connect, then run: yum update kernel* reboot The system stays down. The system [...]Continue Reading »

In particular, I’m wondering if there are any patches or config adjustments made to the disk cache size in the server edition. I’m running on a small system (256M RAM), and would like to experiment with keeping the disk cache size smaller so that there’s more memory available for applications. I’ve found this page at Ubuntu’s website, which neither answers my questions nor is about the 9.04 release. I’m guessing the difference is mostly in [...]Continue Reading »

I’m trying to update the kernel on a CentOS 6 machine with a vanilla 3.1.0-rc10 kernel. It seems to work, except the modules that get created are significantly larger in size than those that come from the distro RPM. Thats an issues, because the mkinitrd command ends up creating a initram file that is 100M (because of the some of all the modules inside) in size. Grub takes forever to load and decompress a 100M [...]Continue Reading »
