Could you please apply this patch so we can see which kind of allocation is failing (patch -p0):
--- ../2.4.9.clean/mm/page_alloc.c Thu Aug 16 12:43:02 2001 +++ ./mm/page_alloc.c Wed Aug 29 23:47:39 2001 @@ -493,6 +493,9 @@ } /* XXX: is pages_min/4 a good amount to reserve for this? */ + if (z->free_pages < z->pages_min / 3 && (gfp_mask & __GFP_WAIT) && + !(current->flags & PF_MEMALLOC)) + continue; if (z->free_pages < z->pages_min / 4 && !(current->flags & PF_MEMALLOC)) continue;
On the assumption it's an atomic allocation, chould you try this patch and see if it reduces the frequency:
