This is definitely improbable ;-). I stopped all processes, except sshd=20 and mingetty (for the console processes), and "lsof" reported no open=20 files. I'd swear it must be a bug, but as you said 2.6.27 (openSUSE=20 11.1) is just too old to take care. =20 > Corrupt attribute fork - matches with the oops signatures. I'd > definitely consider upgrading your kernel as a first step... =20 That's why I wrote "which I planned to migrate". I was just in the=20 process of doing so. This brings me to another question: openSUSE 11.1 is, despite being old,=20 still maintained, so I was under the impression that I'd get updates for=20 problems. But I already received "upgrade your kernel" the last time for=20 my openSUSE 11.2 with it's kernel vmlinuz-2.6.31.12, which by the time=20 was the latest release (in the meantime openSUSE 11.3 got released). So is this just a generic recommendation of developers who love the=20 bleeding-edge stuff and know how many problems they fixed since 2.6.27=20 ("yak, that old stuff, how could it ever run?"), or is it known that not=20 enough fixes go into "maintained" kernels by distributions? I have tons of servers to maintain, and can't compile kernels on my own=20 anymore (I did this when I was younger), so I used openSUSE and I am in=20 the process of replacing servers to SLES, which should receive much=20 better services but still kernel upgrading is not supported on such=20 platforms. So what is the best practice that one should choose when=20 running "long time services" where you can't upgrade all the time? Just curious. :-) =2D-=20 mit freundlichen Gr=FCssen, Michael Monnerie, Ing.
