A "Broken Pipe" (EPIPE) occurs when one end of a communication channel is closed while the other end is still trying to send data. In Zabbix, this typically happens for three reasons:

Ensure max_execution_time is sufficient. Adjust Shared Memory

Check your web server error logs (e.g., /var/log/apache2/error.log or /var/log/nginx/error.log )
