lots of "page allocation failure"

I have lots of page allocation failures in my Ubuntu 12.04 on Toshiba AC100.

Perhaps, we should change the default for/proc/sys/vm/min_free_kbytes -- as suggested in https://bugs.launchpad.net/ubuntu/+source/linux-ac100/+bug/1035208/comments/16 by marvin24 .

What it is now set to:

~ $ sudo cat /proc/sys/vm/min_free_kbytes
2698

How many failures I get:

~ $ sudo cat /var/log/kern.log | fgrep failure | wc --lines
99

I'm afraid it is bad for the system's stability.

I'll try to put

vm.min_free_kbytes = 4096

into /etc/sysctl.d/99-min-free-mem , and see whether they disappear.

Of course, this might not be very good from the other side: this computer has little RAM:

~ $ free -m
             total used free shared buffers cached
Mem: 435 303 132 0 0 15
-/+ buffers/cache: 287 148
Swap: 976 304 672
~ $

, and this setting might cause it to swap in more cases, and cause more resource consumption (CPU and I/O)...
