Expected:
I expect no complaints about open file descriptors by zabbix:
17532:20240704:104341.317 for a discovery process with 5 workers, the user limit of 1024 file descriptors is insufficient. The maximum number of concurrent checks per worker has been reduced to 122
And I also expect zabbix to see the correct number of open file descriptors limit:
