[Bug 971314] Re: 1:4.2.6.p3+dfsg-1ubuntu3 on Precise generates a memory corruption
This bug had me stymied for far too long. When using juju, hostnames can get quite long. For instance, I have instances with names like juju-nick-testopenstack-lhr01-instance-24, and ntp in precise will just hang on installation and prevent juju from even installing the charm. This can be a rather troublesome state to work your way through. ** Tags added: juju -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/971314 Title: 1:4.2.6.p3+dfsg-1ubuntu3 on Precise generates a memory corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/971314/+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 971314] Re: 1:4.2.6.p3+dfsg-1ubuntu3 on Precise generates a memory corruption
I can confirm this too. I wonder if it's somewhat related to bug 941968 Apparently in our case (we use puppet to provision the server), /etc/init.d/ntp start gets stuck (maybe because lockfile-create segfaults?) while the package postinstall script is run, so puppet gets stuck too while provisioning. We've found two ways to workaround the issue: 1. Use shorter hostnames 2. Rename /usr/bin/lockfile-create to /etc/bin/lockfile-create.bak so /etc/init.d/ntp does not find. Restore it back to /usr/bin/lockfile-create after the ntp package install. Both workarounds are somewhat hackish, so it would be great if someone could reproduce it and give it a higher priority :). -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/971314 Title: 1:4.2.6.p3+dfsg-1ubuntu3 on Precise generates a memory corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/971314/+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

Actually, on closer inspection, the error I saw was 'invalid next size', not 'memory corruption'. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/971314 Title: 1:4.2.6.p3+dfsg-1ubuntu3 on Precise generates a memory corruption To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/971314/+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
