Zabbix agent2 high consumption of CPU when added log discovery rule

[ezols]

Good day Zabbix people!

Could I ask your assistance/help with understanding what could be causing cpu load from zabbix agent2.

OS - Ubuntu 22.04 LTS
Zabbix server version - 6.4.0
Zabbix agent2 version - 6.4.4

CPU load appears when I add to host template with discovery rule:

Discovery rule key:

system.run[find /folder/ \( -path '/xxx/xxx' -o -path '/yyy/yyyyyy' \) -prune -o -name '*.log' -print]

Discover rule preprocessing:
JavaScript:

var lld = [];
var lines = value.split("\n");

for (i = 0; i < lines.length; i++) {
  lld.push({
    "{#FILE}": lines[i],
    "{#NAME}": lines[i].split("/").pop().split(".").slice(0,-1).join(".").toUpperCase()
  });
}

return JSON.stringify(lld);

Item prototype key:

logrt[{#FILE},(?!.*errors text|.*skip_import_errors)^.*(ERROR|error|errors$),,,skip]

Trigger prototype key:

last(/xxx APP LOGS/logrt[{#FILE},(?!.*errors text|.*skip_import_errors)^.*(ERROR|error|errors$),,,skip])<>0

Testing:
Launching discover rule system.run command finds the logs:

testing preprocessing script:


Logs are discovered, added to zabbix and triggers working, i just don't understand whats causing 100% load on cpu from zabbix-agent2.
What additional information i should provide to shed some light on this?
