 Description   

It seems that the value of "zabbix[wcache,value,*] are incorrect. Though monitoring just only "Numeric(unsigned)" items, the internal check shows the most processed wcache type is "text". There is no text item in the host. Please see the attached for more infomation.

Could be the same root cause as in ZBX-13030.

Hello!

This behavior has been approved on Zabbix server 3.4.4. In order to reproduce, a plain empty installation of Zabbix is enough.

Regards,
Oleg

(1) We need separate variable for item value type in local history cache. Otherwise we are storing one data type and setting other data type, leading to undefined results.

For example create a trapper item of numeric type and try sending a value to it.
