Out of memory: kill process (mysqld)

MySQL & MariaDB Other MySQL® Questions

Hi,

I have a linux 10.10 with Percona 5.5.17-55-log.

I have used Percona Online Tools for create a config optimized for dedicated server with 10gb ram.

This is the result: [URL=“http://# Generated by Percona Configuration Wizard (http://tools.percona.com/) version - Pastebin.com”]http://pastebin.com/yeKs4AvN[/URL]

I have 10 databases, 5 innodb 5 myisam. (Are game servers)

After 24/48 hours, it starts to eats ram and it kill a mysql process. And DB gets unstable

It generates a syslog [URL=“http://Jul 30 07:08:08 dbserver kernel: 0kB isolated(file):0kB present:7514400kB mlocke - Pastebin.com”]http://pastebin.com/YDuDxXBq[/URL]

The thing is also that, after that event, if I stop mysql remains a memory consumption of 5GB that doesn’t dissapear until i reboot server.

Screenshoots:

Hi,

Can you privide output of these commands during the memory high usage:
ps aux --sort:rss|tail -40
show processlist;
show status like ‘Threads%’;

Also how many tables do you have?
