[Zabbix-users] Zabbix 3.4.3 / MySQL 5.7.2 Stops after 30mins

[Ellis, M. <Mer...@us...>]

Good Morning

I am having a strange problem with a new Zabbix 3.4.3 install.  After 30 mins it seems the Zabbix server stops updating the database.

I have a CentOS 7.4 running on an older dell server, It has 23GB ram, Raid 5 SCSI disk with tons of space:
[cid:image008.png@01D34E34.E8CA6300]
The MySQL database is /home/mysql.

I have php version  5.6.31

My system has:
[cid:image009.png@01D34E35.4440D890]

I have use the mysqltuner.pl to make adjustments in the my.cnf.  I can login to the database after the Zabbix starts failing. If I restart the Zabbix server it starts back working, if I restart the MySQL there is no change.

The only error message I have found is in the mysql.log file:
[Note] Aborted connection 19 to db: 'zabbix' user: 'zabbix' host: 'localhost' (Got an error reading communication packets)

There will be 100's of these.

The zabbix-server processes are still running as well as the MySQL.
Looking in the Zabbix server log it looks normal, like the Zabbix does not know there is a problem, but of course the web interface starts triggering on it is not seeing agent connections after 5 mins (in my case I set this to 15 to cut down on network traffic, this is a WAN install)


If I look at the server performance graphs you can see that one by one the items fall out, not like all at one time, it dies a slow death.
