Re: kernel oops, fast ethernet bridge, 2.4.31

[Willy Tarreau <willy@w.ods.org>]

Hello,

just some basic questions :
  - did your configuration change before the oopses started ? (eg: new
    matches, etc...)

  - did the traffic change recently (protocols, data rate) ? eg: new
    applications on the network, etc...

  - is it possible that it's being targetted by an attack where it is
    installed (unfiltered internet, holiday employees who like to play
    with the network, etc...) ?

I really find it strange that it suddenly started oopsing if nothing
changed. At least it should have been oopsing from day one.

Regards,
willy
