Zabbix agent2 writes to log file /var/log/zabbix/zabbix_agent2.log

Execute command:

mv /var/log/zabbix/zabbix_agent2.log /var/log/zabbix/zabbix_agent2.log.old

The agent2 keeps writing into zabbix_agent2.log.old.
Same thing happens when logrotate moves the file - the agent2 keeps writing to the old file until a restart.

Additionally, it seems that if the file is removed, Zabbix agent2 just stops logging at all, but keeps working.
