The Zabbix Agent repeatedly attempted to connect to the Zabbix Proxy but encountered [connection error (POLLER)] errors. These errors indicated a failure to connect to the specified IP address and port (e.g., 10.142.x.x:10051).
These connection errors occurred frequently, leading to failures in data uploads and configuration updates.
Resource Unavailability Errors:
Concurrently, the Zabbix Proxy logs recorded numerous instances of failed to accept an incoming connection errors. The specific error reported was [11] Resource temporarily unavailable, indicating that the Zabbix Proxy was unable to handle incoming connection requests from the Zabbix Agent due to temporarily unavailable resources.
