CentOS 6.5, KVM, 4GB RAM, 2 cores, kernel: 2.6.32-431.17.1.el6.x86_64 #1 SMP Wed May 7 23:32:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
I'm experiencing a strange memory leak zabbix running from packages installed from http://repo.zabbix.com/zabbix/2.2/rhel/6/ . Right after start of the zabbix-server service, one of the processes – housekeeper – starts taking memory at a decent pace till OOM kicks in. It takes ~2mins to consume all the memory, all of the checks in zabbix have been stopped.
Output from top:
4457 zabbix 20 0 2175m 2.0g 616 S 3.0 52.6 0:04.29 zabbix_server
Process stats:
[root@zabbix01 ~]# ps axwww|grep 4457 4457 ? S 0:05 zabbix_server: housekeeper [removing old history and trends]
Zabbix mysql table is pretty small:
[root@zabbix01 ~]# du -hs /var/lib/mysql/* 1011M /var/lib/mysql/ibdata1 5.0M /var/lib/mysql/ib_logfile0 5.0M /var/lib/mysql/ib_logfile1 988K /var/lib/mysql/mysql 0 /var/lib/mysql/mysql.sock 4.0K /var/lib/mysql/test 1.4M /var/lib/mysql/zabbix
Not sure how to debug this issue, any hints?
