Hi, I tried 2.4.10-pre12 and run some mysql big tests (actually mysql/tests/fork_big.pl ). And, the load is coming up and down from 17 to 6 .... and now, it's 1.7 only and I see in dmesg:
__alloc_pages: 0-order allocation failed (gfp=0x20/0) from c012e3e2 __alloc_pages: 0-order allocation failed (gfp=0x20/0) from c012e3e2
Filename Type Size Used Priority /dev/sda2 partition 2097136 41392 -1
The swap usage grew up from 11MB 40MB.

The system started to page-out when there were almost no buffers available and many cached pages. The system started after bootup with cached=18k or something like that.

I have to say I've been using for a week without any "0-order allocation failed" patch from Marcelo. Now I see am back to the old stage. ;(
