I noticed that and tried using mysqld_safe and it was still killed off. Does the oom killer use the process in the vm or the node? Cause from the node it looks to be run by init:

init-+-atop
     |-auditd---{auditd}
     |-cf-execd
     |-crond
     |-init-+-/usr/local/cpan---spamd\040child
     |      |-atd
     |      |-atop
     |      |-cPhulkd\040-\040proce
     |      |-cf-execd
     |      |-cpanellogd\040-\040sl
     |      |-cpdavd\040-\040accept
     |      |-cpsrvd-ssl
     |      |-crond
     |      |-dovecot-+-dovecot-auth
     |      |         |-3*[imap]
     |      |         |-2*[imap-login]
     |      |         `-2*[pop3-login]
     |      |-exim
     |      |-httpd-+-2*[httpd]
     |      |       |-6*[httpd---26*[{httpd}]]
     |      |       `-leechprotect
     |      |-mysqld_safe---mysqld---24*[{mysqld}]

And I was only using init because thats what the file had itself for most everything in it I just changed the numbers around.
