Queue over 10 min does not reduce after switching to Active Agents
Hello there, I new here and this is my first question. First of all, I will start that I'm new to zabbix, previously I was working only with Prometheus. In my current company I'm able to admin zabbix. Previously we have migrated from stanalone zabbix server to zabbix cluster with 2 zabbix servers and remote DB.
We find out that passive checks generate lots of connections on our monitored servers, and amount of items on each node depends from 1k to 4k, so we decided to switch to active agents. Our servers was monitoring by zabbix proxy(proxy groups for HA), default config of each proxy is 4 CPU, 4 GB memory, 60 disk space and 2GB swap, and config files on proxies almost identical
After updating templates and configuration files on monitored nodes, I figured out that proxy queue over 10 minutes grown, but only for 2 proxies(both in one proxy group).
I have done so many tries to fix this( increasing trappers, dbsyncers, processors etc), but this did not solve the problem. I even tried to send data manually by hands making dump and sending data to server using zabbix_send (sound silly, I know 
). My graphs shows, that my proxy does not load at all:

​My zabbix server is 7.0.19 version, version of zabbix proxies I have problem with is 7.0.22. I'm begging for help, tired of struggling with this
