What Jessie Did Next...

...being the inane ramblings of a mundane Yorkshire bird.

I’ve recently noticed a spate of problems with a keepalived install which I’m using to distribute load over several application servers, manifesting itself as:

[874439.982041] keepalived[7079]: segfault at 0 ip 0804d5fe sp bf976e80 error 6 in keepalived[8048000+20000]
[874439.987336] keepalived[7081]: segfault at 0 ip 0804d5fe sp bf976e80 error 6 in keepalived[8048000+20000]
[874439.992815] keepalived[7083]: segfault at 0 ip 0804d5fe sp bf976e80 error 6 in keepalived[8048000+20000]
[874444.956732] __ratelimit: 534 callbacks suppressed

This is using Debian 6.0.1 (squeeze) on i386 architecture.

After lots of digging around it seems the answer is simply that the module ip_vs isn’t loaded.

To fix, just do:

# modprobe ip_vs

It’ll stop the segfaults and all will be returned to sweetness and light.

(This post is intentionally Google-fodder. Hope this helps someone else with the same issues.)

  1. I think that in future Debian packages of keepalived, the package will handle the modprobe for this. See this bug:
