: View current system limits for shared memory and semaphores. 4. Network & External Scripts

If the Zabbix database is locked or slow, the server process might hang. When the frontend waits too long for the server to process a request, the socket connection times out and "breaks." Check for long-running SQL queries. Ensure the database has enough connections available. Common Fixes Increase Timeout Settings

In some containerized or cloud environments, NAT or TLS overhead can cause sudden connection drops between the server and its internal listeners. How to Fix It 1. Increase the Open Files Limit

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 cannot write to ipc socket broken pipe upd

If the preprocessing service stops (due to memory leaks or bugs in specific versions like 6.0 or 7.0), other processes trying to send data to it will fail with this error.

Note: After modifying these values, restart the Zabbix server service ( systemctl restart zabbix-server ). 2. Optimize Kernel and System Limits

Investigate the specific service mentioned in the logs immediately following the broken pipe message (e.g., "cannot connect to preprocessing service"). cannot write to IPC socket: Broken pipe - ZABBIX Forums : View current system limits for shared memory

This error typically appears in Zabbix server or proxy logs, often accompanied by warnings about pollers, discoverers, or other child processes dying.

A error occurs when one process attempts to write data to an IPC socket, but the process on the receiving end has already closed the connection abruptly, crashed, or timed out. Top 4 Root Causes of Zabbix IPC Socket Failures 1. Preprocessing Worker Crashes (Out of Memory) When the frontend waits too long for the

: If the system runs out of available file descriptors or memory, the kernel may kill processes or drop socket connections abruptly. Service Timeouts

If you find segmentation faults, it is highly recommended to upgrade your Zabbix Server/Proxy to the latest patch version, as segfaults are usually bugs that the Zabbix team has identified and patched. If the issue persists, collect a core dump and reach out to the Zabbix Support team. Step 2: Review Cache and Queue Metrics

The communication took too long, and the system or Zabbix killed the connection.

UDP (User Datagram Protocol) is a transport-layer protocol used for sending data over IP networks. It is a connectionless protocol, which means that there is no guarantee of delivery, and packets may be lost or corrupted during transmission.
