Hi guys, could we include a configuration at mysqld_mult and mysqld_safe?

at linux killing the mysqld process is a big problem, i prefer leave it
as the last process to kill

check this post
:http://www.oracle.com/technetwork/articles/servers-storage-dev/oom-killer-1911807.html

in this case oracle is the last tprocess to kill

they use the /proc kernel interface to set the oom_adj

that's a deprecated interface and i had something similar years ago inthe sysvinit-script but after more than 4 years systemd:


LimitNOFILE=infinity
LimitMEMLOCK=infinity
OOMScoreAdjust=-1000
