High Queue - Proxy with Active Agents

[mornevr]

Hi,

I apologize if this has been answered but I have not found a solution in the other posts.

I have a Zabbix Server (Single Host for Web, Server and DB) which will end up having around 40 proxies feeding into the server. As it stands, I have 7 x proxies deployed with varying host counts being monitored. Strangely, the Proxy I am having issues with is configure for mostly Active Agent Monitoring along with some MSSQL passive monitoring.

My Proxy server runs on Debian 12 (2 x vCPU, 6GB RAM and 70GB HDD) and an SQLite3 database. I am clueless as to what to tune as I can see no poller issues anywhere. Can someone please guide me as to what can be the issue and what I am doing wrong?

Further to this, I have a Proxy with only passive agents deployed which queue is almost always empty. Please help me make sense of this as my understanding is that using active agents is the best way to go about this.

Could you solve it? If so, can you please share your learnings?
