[Bug 1028682] Re: precise uec builds eat 100% cpu on launch, check-apt and rsyslogd
Thanks for reporting this. It is quite an old bug now, and probably did not get any attention because it was not assigned to a package. Having said that, I am not sure which is the right package to assign this bug to. Therefore I am assigning it to cloud-init, as I found a similar type of bug where this was done. If it is the wrong package, then hopefully someone looking at cloud-init bugs will have a better idea where to assign it so that it is followed up. Also, as it is so old, perhaps the problem was fixed/went away in the meantime? Do you still see this problem? ** Package changed: ubuntu = cloud-init (Ubuntu) ** Changed in: cloud-init (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1028682 Title: precise uec builds eat 100% cpu on launch, check-apt and rsyslogd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1028682/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 1028682] Re: precise uec builds eat 100% cpu on launch, check-apt and rsyslogd
The initial hang for ssh logins may be due to /etc/update-motd.d trying to dynamically create a new motd and running updates-available. The UEC images assume there is a host resolvable called ubuntu- mirrir.localdomain, which is not always necessarily the case. Since these are typically short-lived ephemeral instances, reaching out to the Internet to retrieve package information as part of the motd creation process seems like a greater risk than benefit. Adding rsyslog stop to rc.local might address the problems opening /proc/kmsg and spinning at 100% CPU. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1028682 Title: precise uec builds eat 100% cpu on launch, check-apt and rsyslogd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1028682/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1028682] Re: precise uec builds eat 100% cpu on launch, check-apt and rsyslogd
I have verified that clearing out most of the dynamic content relying on Internet-facing connectivity from update-motd.d and adding /sbin/stop rsyslog to rc.local does solve the bug. I suspect the problem with rsyslogd spinning at 100% cpu is a regression from Lucid, where kmsg is only accessible to root, but the process is running with reduced privileges and not detecting the problem. # mount -o loop precise-server-cloudimg-amd64.img /mnt # cd /mnt/etc # vi rc.local add /sbin/stop rsyslog to rc.local # cd /mnt/etc/update-motd.d # rm 90-updates-available # rm 91-release-upgrade # rm 98-reboot-required -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1028682 Title: precise uec builds eat 100% cpu on launch, check-apt and rsyslogd To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1028682/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
