Zabbix 6.2.3 PGSQL DB error

[dissmissed]

hi everyone, i apoligies for my bad english..

we create a new zabbix server and follow logs ;

[select i.itemid,a.name from applications a,items_applications i where a.applicationid=i.applicationid and i.itemid=23274]
265:20221202:081655.092 [Z3005] query failed: [0] PGRES_FATAL_ERROR:ERROR: relation "applications" does not exist
LINE 1: select i.itemid,a.name from applications a,items_application...

when i compare zabbix server v5 web ui it's seen there

and in zabbix 6.2.3 not there

how to fix this error?

yes.. Applications were converted to tags.
I suppose that is a frontend query... are you trying to use v5 frontend with v6 DB? Otherwise I would not see any case to have such query...

hi.. no,there are we installed the zabbix server 6.2.3postgresql and 6.2.3 proxy postgresql

[cyber]

Running frontend on same host? Also installed zabbix-web-pgsql package?

Hello, yes the infrastructure build with docker and the packages like in the following line;

timescaledb-pg13:2.7.2
zabbix-server-pgsql:ubuntu-6.2.3
zabbix-web-apache-pgsql:6.2.3

Here is a full log line;

[select i.itemid,a.name from applications a,items_applications i where a.applicationid=i.applicationid and i.itemid=50999]
266:20221206:121600.638 [Z3005] query failed: [0] PGRES_FATAL_ERROR:ERROR: relation "applications" does not exist
LINE 1: select i.itemid,a.name from applications a,items_application...

It's a fresh installation and we know in zabbix 6 there is no more applications.

This log occurs a few times in just a one second. So disks are quickly getting bigger..

Need your help
