Problems after upgrade 3.2 > 3.4.11

[christovam]

I was running zabbix 3.2 and upgraded to version 3.4.11. I always compile the version using ./configure + parameters and update the frontend files since version 1.8.

After this upgrade several items collected by the Zabbix Agent or SNMP are not being updated. Many values are empty.
If I run via CLI, I can collect the value correctly. "/ usr / local / zabbix / bin / zabbix_get -s 200.xxx.xxx.xx -k system.boottime
1528713106 "

In the dashboard, in the latest date, the items are without values. I already recompiled the zabbix server, I changed the server zabbix Frontend. But it still did not work out.

Is someone going through this?

zabbix_server.log file plus Zabbix internal graphs might give you more clues here.
