 Description   

Steps to reproduce:

  1. Upgrade from zabbix 6.0.29 to 7.0.4

Result:
Looks like preprocessing manager consumes memory to the end.

See output of "ps" at one hour intervals and memory consumption graph.

What debug info can I additionally provide?

Same issue on Zserver 7.0.3, with preprocessing manager process getting as high as ~40% of RAM usage.
