Did you do a 'swapoff' at some point before this?
No, I didn't change anything. I just put stress on it with ab to test the machine but it felt down :-((
Others ideas ?
Thanks
Samuel

The memory corruption you saw usually (almost always) indicates a hardware problem. It may not have shown up during normal usage because without ab your RAM has more idle time and can keep up refreshing itself easily.
Flakey mainboard chipsets could "forget" about such
things under heavy DMA load, or ... (who knows)
Setting the BIOS settings one notch more conservative often fixes these marginal errors.

Rik

I asked about the swapoff path because I have a couple of stable MP boxes that exhibit swap map corruption (similar to what he appears to be seeing) during/after a swapoff operation in 2.4. I presented a patch a couple weeks ago that fixes some of the problems that I am seeing. A quick look at 2.2.19 makes it look the same problems might exist there as well. If he isn't doing swapoff then my fixes probably won't help him.
