VERY INTERESTING !
Hi again !
I think, this looks like a memory leak. How much memory do you have ?
Check if you have added a "mem=" kernel parameter by accident.
What tool have you used to prepare the kernel. Wich parameter du you
have used ?
The interesting points are:
"VM: killing process XXXXX"
and
"bash: out of virtual memory"
Perhaps it is a good idea to check the kernel itself. For example, if
your
target (client) has a floppy drive, do following hack. Do a `dd' of the
kernel
on a floppy
dd if=/tftpboot/.../vmlinuz of=/dev/fd0 bs=512
and boot from floppy. The create a "dummy" device, which has the major 0
and
minor 255, like
mknod /dev/nfs c 0 255
on the linux host. After that use
rdev /dev/fd0 /dev/nfs
... so the kernel is patched to boot from major 0 and minor 255.
(Another way is to edit with a hex editor the space, where the kernel
saves
major and minor of the boot device).
Boot the client from floppy and everything should work (?!)
If the problem further exists, check the kernel setup (make xconfig in
the
kernel source directory), check especially the first menu pages
concerning
the RAM.
AND: Before you do anything, read the kernel informations on the screen,
when
ther kernel starts to boot, if there is anything, which seems to be a
problem.
With friendly regards
