Understanding the root cause requires looking at how Zabbix handles Inter-Process Communication (IPC). What Causes the "Broken Pipe" Error?
Security modules can sometimes block Zabbix processes from writing to sockets in /tmp or /var/run/zabbix .
The Zabbix server or proxy daemon crashed while receiving data. zabbix cannot write to ipc socket broken pipe upd
Temporarily set SELinux to permissive mode to test if the error disappears. If it does, you will need to create a custom policy module. 🛠️ Key Takeaway
Look for "Out of memory," "Connection refused," or "Slow query" messages immediately preceding the IPC error. 3. Review Database Performance Understanding the root cause requires looking at how
A "Broken Pipe" (EPIPE) occurs when one end of a communication channel is closed while the other end is still trying to send data. In Zabbix, this typically happens for three reasons:
Are you using a , or is this a direct server setup? The Zabbix server or proxy daemon crashed while
The system ran out of memory or file descriptors, forcing the socket to close. Troubleshooting Steps 1. Check Service Status
The communication took too long, and the system or Zabbix killed the connection.
