Proxy Memory keeps climbing

[LukeAB93UK]

Hello,

I have a problem I can not seem to figure out.

We have a Zabbix infrastructure using 4x Proxies all on Alma Linux 9.4 running the latest 7.0.4 version and 1x of the 4x Proxies memory usage keeps climbing but the other 3 are not.

This proxy has 12GB of memory assigned to it, pulls around 1280 Values per second. I am not entirely sure whats eating all the memory as the proxy did not have this issue when running on 6.4.

And what process is that 2682850, that seems to be using most of the memory?

It appears to be the Pre-processors

How come you have som many preprocessing managers? There should be one manager and multiple workers, as long as I know..

This is the only reference to "preprocessors" in zabbix_proxy.conf and I have left it all default

That looks OK... But your process list on previous pic definitely shows "managers"..
