This error ( cannot write to IPC socket: broken pipe ) in Zabbix usually points to a communication breakdown between the Zabbix server (or proxy) and the Zabbix agent, or between Zabbix processes themselves. Here’s a to diagnose and fix it. zabbix cannot write to ipc socket broken pipe upd

Check the limits for the Zabbix user:

sudo systemctl daemon-reload sudo systemctl restart zabbix-server The communication took too long, and the system

in your system logs and upgrade Zabbix if necessary. Optimize your database to handle the influx of metrics.

A: Check if other limits are in effect. Some systems require both ulimit -n changes in /etc/security/limits.conf and LimitNOFILE in systemd. Also verify that your Zabbix version supports the limits you've set. Check the limits for the Zabbix user: sudo

Increase the file descriptor limits for the zabbix system user. Open your system limits configuration file: sudo nano /etc/security/limits.conf Use code with caution.

Zabbix processes need many file descriptors (sockets, pipes, DB connections).

The error occurs in Zabbix when an internal Zabbix process tries to communicate with another local service component—most frequently the preprocessing service —but finds that the receiving end of the communication channel (the Unix socket) has closed unexpectedly. This issue often causes the Zabbix server daemon to crash, freeze, or become unresponsive shortly after a system restart, platform migration, or major version upgrade.
