| |
My machine OOM'd during a run of 2 simultaneous dbench 512's on 2 separate 12GB tmpfs fs's on a 32x NUMA-Q with 32GB of RAM, 2.5.35 plus minimalistic booting fixes, no swap, and my recently posted false OOM fix (though it is perhaps not the most desirable fix).
Note: gfp_mask == __GFP_FS | __GFP_HIGHIO | __GFP_IO | __GFP__WAIT ... the __GFP_FS checks can't save us here.
Cheers, Bill
