The error message "cannot write to IPC socket: broken pipe (UDP)" is a signal of internal congestion or architectural misalignment within the Zabbix server. It highlights the fragile balance between high-speed data ingestion and the slower, heavier process of database persistence. By understanding the IPC mechanisms and identifying whether the bottleneck lies in the Operating System buffers, the database performance, or the process management, administrators can restore stability. Ultimately, resolving this error is not merely about fixing a broken connection; it is about optimizing the monitoring infrastructure to handle the scale of modern data streams.

If running Zabbix as a systemd service, you may also need to add LimitNOFILE=4096 to your service unit file (e.g., zabbix-server.service ) to ensure the limit is applied at startup.

The error in Zabbix typically occurs when the Zabbix server or proxy process hits the operating system's limit for open file descriptors . This prevents internal processes (like the preprocessing worker) from communicating, causing the "Broken pipe" signal when one end of the communication channel closes unexpectedly.
