      Since the upgrade from Zabbix 7.0.13 to 7.0.14 I experience high CPU load on Ubuntu based Zabbix nodes (both server and proxy). One of my proxies is based on Debian 12 and uses the exact same configuration as the Ubuntu proxy, but the Debian based proxy isn't experiencing high CPU loads.

      The preprocessing manager both on proxy and server are the ones generating this cpu load.

      I'll attach some screenshots of the Zabbix server and health dashboard for this:
