Willy,
Hmm ... could be, but I don't think so. I use last mysql3 version and
I have this problem without mysql too.

For example on this box there is no mysql (Piv 2.4GHz/512Mo):
__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
VM: killing process watchdog
__alloc_pages: 1-order allocation failed (gfp=0x1f0/0)
__alloc_pages: 0-order allocation failed (gfp=0x1d2/0)
VM: killing process watchdog

# free

Mem: 514468 508416 6052 0 11608 205464
-/+ buffers/cache: 291344 223124

When I swithed more that 700 servers 10-15 days ago to 2.4.23, I saw that
servers swaped less that with 2.4.22. So I believe VM was modified. Cool.
Great job. Now servers begin to crash :/
