strange messages & syste freeze

["Alex" <alex hostingcenter ro>]

Does anybody know what does this mean?

__alloc_pages: 0-order allocation failed (gfp=0x20/1)
__alloc_pages: 0-order allocation failed (gfp=0x20/1)
__alloc_pages: 0-order allocation failed (gfp=0x20/1)
__alloc_pages: 0-order allocation failed (gfp=0x20/1)
__alloc_pages: 0-order allocation failed (gfp=0x20/1)
__alloc_pages: 0-order allocation failed (gfp=0x20/1)
__alloc_pages: 0-order allocation failed (gfp=0x20/1)
__alloc_pages: 0-order allocation failed (gfp=0x20/1)
__alloc_pages: 0-order allocation failed (gfp=0x20/1)

Whe this happens, the sistem is 0.0% idle and not even ping I don;t have on
that server. Kernel 2.4.23 & cck patches applied:
patch-2.4.23-ckbase-0312022106
patch-2.4.23-ckbase-rl2-0312021358
patch-2.4.23-rl2dt-vhzj64-0312022318

What could be the cause for this behaviour?
