[Bug 160426] Re: keepalived using genhash keeps getting "zombied" and using CPU to a 100%
Adam, thanks for the response! With that, I'll mark it as Confirmed. The symptoms all seem to center around the order that modules are loaded and perhaps how networking is handled. Perhaps keepalived needs to be delayed until after all networking. I have to wonder if this still affects 12.04, since runlevel 2 is now delayed until all interfaces in /etc/network/interfaces have been brought up. ** Changed in: keepalived (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to keepalived in Ubuntu. https://bugs.launchpad.net/bugs/160426 Title: keepalived using genhash keeps getting "zombied" and using CPU to a 100% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keepalived/+bug/160426/+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

There is clearly more than one reporter (I'm one of them). I worked around it by compiling from source. Keepalived IF you are using it is liking to be a HIGHLY critical service (I am not currently but will again). Maybe it's still a medium but just to put a counterpoint to your comment Clint. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to keepalived in Ubuntu. https://bugs.launchpad.net/bugs/160426 Title: keepalived using genhash keeps getting "zombied" and using CPU to a 100% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keepalived/+bug/160426/+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

Setting Importance to Medium. 5 year old bug that has only one reporter, so the scope of the impact seems fairly limited. ** Changed in: keepalived (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to keepalived in Ubuntu. https://bugs.launchpad.net/bugs/160426 Title: keepalived using genhash keeps getting "zombied" and using CPU to a 100% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keepalived/+bug/160426/+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

Yes, this porblem happens right after a reboot and if I try to restart the service result the same. I'm obtaining an IP dynamically by VRRP. It has one statically configured IP and additionally gets second if this computer becomes master router. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to keepalived in Ubuntu. https://bugs.launchpad.net/bugs/160426 Title: keepalived using genhash keeps getting "zombied" and using CPU to a 100% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/keepalived/+bug/160426/+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 160426] Re: keepalived using genhash keeps getting "zombied" and using CPU to a 100%
Hi there, Does this problem only happens right after a reboot? IIRC, this might be related to having keepalived after networking is started. it is up to upstart/sysvinit to start the daemon, and then this happens? Are you obtaining an IP address with DHCP or is it statically configured? Could you try to stop and restart the service and see if the issue is seen again? Thank you in advance!
