Not sure what this is. Maybe the slowing SLUB solves the race. Could you try and boot with slub_debug=F to enable limited debugging? > cc1 invoked oom-killer: gfp_mask=0x1201d2, order=0, oomkilladj=0 Regular Order 0 alloc .... but why is there no memory available , reclaimed? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
