I recently upgraded to 6.4.6 (all components) but I am seeing a log of "zabbix docker failed to fetch info data" since a few days for several hosts. Is this a known issue with 6.4.6? I didn't have these with 6.4.4. I am using the official docker containers.

I went back to 6.4.5 for the server container and the problem is gone. Clearly has to do with the 6.4.6 server container

If you think you have found a bug or defect, you can rise a ticket here https://support.zabbix.com/browse/ZBXComment

I now believe that it has nothing to do with 6.4.6. It seems that the cause was elsewhere, but I do not understand the actual causal relation. On the same host where the Zabbix-server is running I also have a syslog-ng server. I had a missing ";" in the syslog-ng config file after some testing, so syslog-ng was not actually running. I have no idea why that would impact Zabbix that much.Comment

That also was not the problem.. my current theory is that it is a performance problem with the Zabbix server, no ides why that started abruptly at some point in time. I will open another post for the performance issue.Comment

It's also a good idea to review your Docker configurations, ensure network connectivity, and verify if any changes were made to your setup during the upgrade that might be causing this issue.Comment
