SubjectLinux 2.4.4 folks
Hello linux-kernel,

I've trying to move some of my servers to 2.4.4 kernel from 2.2.x.
Everything goes fine, notable perfomance increase occures, but the
problem is I'm really often touch the following problem:

__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.
__alloc_pages: 1-order allocation failed.

This message may also show 1-order, 0-order, 3-order failures (only
one type at the time). This problems also appeared then I tried to
use 2.4.1-2.4.3 kernels.

This sometimes leads to system hang, sometimes some processes gets
unkillable (even by kill -9) and in some cases I do not see any bad
results from this, but still this does not looks the right thing to
happen.

The problem is the systems this happens on are not short of memory.
Here is the free output for the system I had this happened this
morning:

rat:~ # free
total used free shared buffers cached
Mem: 1028628 1025820 2808 0 9340 332412
-/+ buffers/cache: 684068 344560
Swap: 2097136 0 2097136


Does anyone has any ideas about this problem ?
