Hi, On some situations, such as bug 139648, we have to use a large min_free_kbytes vaule to prevent oom killer being triggered when running stress tests. So looks like a large min_free_kbytes is needed. And I think this bug isn't a problem of min_free_kbytes too large. It is because that when performing kdump, the value is read from /etc/sysctl.conf. If we can change this (don't using min_free_kbytes of /etc/sysctl.conf), this bug can be fxied. Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1528101 Title: ISST-LTE: kdump failed: second kernel booting hangs after /scripts /init-bottom when large min_free_kbytes value being set To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kexec-tools/+bug/1528101/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
