Hello Ján, Could you please gather network dump from this host during failing checks? tcpdump -npi any -s 0 -w /tmp/ZBX-21766.mongodb.pcap port 27017 Start capturing, execute check several times using zabbix_get or execute now from frontend. Regards, |

Thank you, Please show: ss -twlrnu ip a cat /etc/hosts Looks like sometimes agent tries to create new connection on top of existing one. |

Hi, logs from zabbix-agent2
2023/10/13 15:08:23.646013 [MongoDB] server selection error: server selection timeout, current topology: { Type: Single, Servers: [
{ Addr: mongodb.mycompany.internal:27017, Type: Unknown, Last error: connection() error occured during connection handshake: connection(mongodb.mycompany.internal:27017[-188093]) socket was unexpectedly closed: EOF }
, ] }
When doing zabbix_get sometimes it responds
