: Execute the actual data processing tasks assigned by the manager.

If you're currently experiencing this issue and want to narrow it down further, consider checking the following:

If the value is low (e.g., 1024), increase it. Edit /etc/security/limits.conf and add: zabbix soft nofile 65535 zabbix hard nofile 65535 Use code with caution. zabbix cannot write to ipc socket broken pipe upd

Do you have access to the /var/log/zabbix/zabbix_server.log to check the exact lines preceding the error?

If a specific service (e.g., zabbix_preprocessing ) crashes or is killed by the OS (such as by the OOM killer), other processes trying to send it data will receive a "Broken pipe" error.

This "Broken pipe" error is a symptom, not the disease. By following this troubleshooting guide, you can diagnose and resolve the underlying cause, leading to a more reliable monitoring infrastructure. Implement the fixes in a planned maintenance window or a non-production environment first. webMethods Knowlegebase : Broken Pipe Errors (1716831) -

If you just need to silence the flood of errors while investigating:

Large‑scale deployments, particularly those with or a very high number of active items, can overload the preprocessing system. When the preprocessing manager or its workers cannot keep up with the incoming data flow, they may time out or crash, leaving other processes with a broken pipe. The same can happen if network latency or packet loss affects communication between a Zabbix proxy and its server, causing the TCP connection to be terminated prematurely.

The "Broken Pipe" error is rarely a bug in the code; it is almost always a symptom of a or a timeout . Focus your efforts on the health of the zabbix-server process and its ability to talk to the database. If you'd like to dive deeper, let me know: Do you have access to the /var/log/zabbix/zabbix_server

kernel.msgmnb = 65536 kernel.msgmni = 2048 kernel.msgmax = 65536 Use code with caution. (Apply changes with sudo sysctl -p ) . Conclusion

Stray processes from the old binary version often hold onto IPC sockets, causing "Broken pipe" errors for the new binary.
