Data loss

[walter]

Hi,

My zabbix version is 3.4.0.
On the same host, some items will become no data, others are still normal. if I disable and enable it, the item become normal again.
there is no error on web, the agent is always ok, the command line on server is always successful, too.
I used Atlas as mysql proxy, one master and two slave.

I hope someone can help.
Thanks in advance.

Regards
walter
