This is definitely improbable ;-). I stopped all processes, except sshd
and mingetty (for the console processes), and "lsof" reported no open
files. I'd swear it must be a bug, but as you said 2.6.27 (openSUSE
11.1) is just too old to take care.

That's why I wrote "which I planned to migrate". I was just in the
process of doing so.
This brings me to another question: openSUSE 11.1 is, despite being old,
still maintained, so I was under the impression that I'd get updates for
problems. But I already received "upgrade your kernel" the last time for
my openSUSE 11.2 with it's kernel vmlinuz-188.8.131.52, which by the time
was the latest release (in the meantime openSUSE 11.3 got released).
So is this just a generic recommendation of developers who love the
bleeding-edge stuff and know how many problems they fixed since 2.6.27
("yak, that old stuff, how could it ever run?"), or is it known that not
enough fixes go into "maintained" kernels by distributions?
I have tons of servers to maintain, and can't compile kernels on my own
anymore (I did this when I was younger), so I used openSUSE and I am in
the process of replacing servers to SLES, which should receive much
better services but still kernel upgrading is not supported on such
platforms. So what is the best practice that one should choose when
running "long time services" where you can't upgrade all the time?
Just curious. :-)
