If you're currently experiencing this issue and want to narrow it down further, consider checking the following:
systemctl start zabbix-server
I’m encountering an intermittent error in my Zabbix setup when monitoring certain :
If the above configuration adjustments do not solve the problem, you may need to dig into the Linux IPC limits.
This command temporarily disables SELinux. zabbix cannot write to ipc socket broken pipe upd

But to fix root cause.
The communication took too long, and the system or Zabbix killed the connection.
IPC sockets need disk space and inodes.
The error in Zabbix typically indicates that a Zabbix process (like the server or proxy) attempted to communicate with a internal service (like the preprocessing manager) that had already closed its connection. Core Causes
IPC (Inter-Process Communication) socket is a method of communication between processes on the same system. It allows different processes to exchange data, and in the context of Zabbix, IPC sockets are used for communication between the Zabbix agent and the Zabbix server.

If you see this error, you need to determine which component is failing. Step 1: Examine Zabbix Logs If you're currently experiencing this issue and want
If history syncer is the bottleneck, increase the number of processes:
On server:
This is the most common reason the internal socket "breaks." When Zabbix hits its operating system limit for open files, it can no longer maintain IPC (Inter-Process Communication) channels. Increase the for the Zabbix user. Check current limits with cat /proc/ /limits | grep open and adjust them in /etc/security/limits.conf (e.g., set to 4096 or higher).
