Upon upgradeing to 6.2.9, the Asterisk AMI integration becomes broken / unreliable. Worked with lower versions.

Asterisk template: https://git.zabbix.com/projects/ZBX/repos/zabbix/browse/templates/tel/asterisk_http?at=refs%2Fheads%2Frelease%2F6.2

Steps to reproduce:

1. Upgrade 6.2.x to 6.2.9
2. Navigate to Latest Data
3. The template's GetStats item (JavaScript collecting all metrics) generates the error below in the Info column

Result:

{{{{Preprocessing failed for: HTTP/1.1 200 OK..Server: Asterisk/18.16.0..Date: Thu, 30 Mar 2023 06:35:34 GMT..Cache-Control: no...}}}}
{{{{1. Failed: Error: log exceeds the maximum size of 8388608 bytes.}}}}
{{{{at [anon] (zabbix.c:83) internal}}}}
{{{{at [anon] () native strict preventsyield}}}}
{{{{at [anon] (function:10)}}}}
{{{{at [anon] (function:294) preventsyield}}}}

Consequently, the related Items contains data sporadically. The whole template becomes unreliable.

No AMI related changes were introduced on the Asterisk before the incident started to happen.

I noticed similar Zabbix tickets with other recent versions too, and not just with the Asterisk template. This might be a bit more widespread issue with some recent Zabbix internal (memory?) limit changes...

Zabbix server: Ubuntu 20.04.6 LTS in Azure VM
