Mysql gets killed and shutdown all my website

[tomtom]

Hello, i have 2gb vps with centos 6 and vestacp and i'm hosting few websites. Sometimes there are random crashes of the database and almost all of my websites gets shutdown and it is really frustrating.. Maybe you can help me find a reason why. innodb buffer size is 1GB.

with command top:


with free -m


grep -i 'killed process'


I know from this that my database get killed but why? and how to prevent it.. If you need any more logs please ask. Any help is appreciated because i'm fighting this for a long time..

Also there is var/log/messages in pastebin:
