Zabbix Cannot Write To Ipc Socket Broken Pipe Upd

Increase if needed:

When Zabbix cannot process incoming data fast enough, the history cache fills up. The history syncer process may fail or become overwhelmed, closing the IPC pipe. zabbix cannot write to ipc socket broken pipe upd

This happens specifically for UDP checks (e.g., SNMP traps, custom UDP data collection). TCP items seem unaffected. Increase if needed: When Zabbix cannot process incoming

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. Understanding Inter-Process Communication (IPC) in Zabbix TCP items seem unaffected

Ensure the Zabbix user has permission to open enough simultaneous files and sockets. Create a systemd override for the service: sudo systemctl edit zabbix-server Use code with caution.
