[Zabbix server] Some hosts no more trigger Problems

[Frogg]

Hi,

I have searched on the forum and internet, and didn't find anything about it, so i post here my problem

Version:
I am using the appliance iso 4.4.4 i updated it to 4.4.6 to try to solve the problem without success.

Trouble:
I already re-installed 2 times Zabbix with the same trouble. After reinstalling all is working well, then after around 1 month the problems aren't refreshing in the web interface for some host.

- lastest data are up to date
- Queue is empty

It is like triggers are not triggering for some hosts.

I cant find logs with error

serverlog (today after updating to 4.4.6 but no error was sent in previous version too):
