Public bug reported:
When I'm doing something memory intensive such as compiling a large
project I find that I start getting processes killed (mainly Chrome),
despite there still being a large amount of swap free. At first I
thought this was being done by the normal Linux oom-killer, but it's
actually the Android low memory handler driver which is built into the
default Ubuntu kernel configuration. Example of the messages I get in
syslog when a process is killed:
Jul 31 11:04:34 asmith-linux kernel: [84686.869462] select 8851 (chrome), adj
300, size 18339, to kill
Jul 31 11:04:34 asmith-linux kernel: [84686.869479] send sigkill to 8851
(chrome), adj 300, size 18339
When this happens, although main memory is close to full, my swap is
barely utilised at all - I have an 8GB swap partition, but I've yet to
see more than around 1GB of it get used.
Kernel version: Ubuntu 3.8.0-27.40-generic 3.8.13.4
