[Bug 1038570] Re: lots of "page allocation failure"
The filename I have suggested to put this setting to was wrong
(/etc/sysctl.d/99-min-free-mem); it would be correct to name it
/etc/sysctl.d/99-min-free-mem.conf (as described in
/etc/sysctl.d/README: "End-users can use 60-*.conf and above").

lots of "page allocation failure"
Status in Enablement project for the Toshiba AC100 NetBook:
Status in “linux-meta-ac100” package in Ubuntu:
I have lots of page allocation failures in my Ubuntu 12.04 on Toshiba
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
How many failures I get:
~ $ sudo cat /var/log/kern.log | fgrep failure | wc --lines
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)...
