This comprehensive guide diagnoses the root causes of this Inter-Process Communication (IPC) failure and provides step-by-step remediation strategies. Understanding the Error: What is an IPC Socket Broken Pipe?
IPC sockets utilize system memory buffers. If your Zabbix server is processing a massive influx of data (e.g., a network storm or mass agent autodiscovery), the IPC buffer may fill up.

(Remember to restart the Zabbix server service after making changes). Step 3: Tune Your Database Parameters
Check if all Zabbix daemons are running with ps ax | grep zabbix . 3. Adjust Preprocessing Settings
Edit the Zabbix service file:
dmesg -T | grep -i -E 'oom[-_]killer|killed' # OR grep -i 'killed' /var/log/messages grep -i 'killed' /var/log/syslog Use code with caution.
This is by far the most frequent cause of the “broken pipe” error on Linux systems that use (most modern distributions). The system-wide setting RemoveIPC=yes (the default in /etc/systemd/logind.conf ) is designed to clean up IPC objects— System V semaphores, shared memory, and message queues —when a user fully logs out.
