Zabbix Cannot Write To Ipc Socket Broken Pipe Upd High Quality -

Check the cache usage (e.g., Value cache, History cache). If these are at 100%, the internal IPC queues will begin to fail.

#!/usr/bin/env python3 import requests # may not be installed print(requests.get('http://localhost/metric').text)

Mismatched timeouts are the #1 reason for broken pipes on active checks. zabbix cannot write to ipc socket broken pipe upd

The Zabbix server log shows preprocessing worker #X started followed shortly by a crash or socket error. The Fix:

: Ensure your database isn't hitting connection limits, as this can cause Zabbix child processes to exit prematurely. Step 4: Verify Socket Permissions Check the cache usage (e

If custom JavaScript or external verification takes too long, raise the core execution time limit within the same configuration file: Timeout=4 Use code with caution. 3. Shared Memory Allocation Flaws

Increase the Timeout parameter in both zabbix_server.conf and zabbix_agentd.conf or zabbix_agent2.conf . The default is often 3 seconds, which is insufficient for heavy scripts or slow database queries. Timeout=10 # Try increasing to 10 or 30 seconds max Use code with caution. 3. Database Bottlenecks and Slow Operations The Zabbix server log shows preprocessing worker #X

Ensure the directory containing the Zabbix sockets (usually /tmp/ or /var/run/zabbix/ ) has correct permissions ( zabbix:zabbix ) and isn't running out of disk space. Conclusion

Open /var/log/messages , /var/log/syslog , or run journalctl -xe . Look for oom-killer terminating zabbix_server processes at that exact timestamp.
