Not that i can think of. I'm using PHP 7.4 FPM and CLI. Here are the relevant php.ini entries:
extension=/opt/elastic/apm-agent-php/extensions/elastic_apm-20190902.so
elastic_apm.bootstrap_php_part_file=/opt/elastic/apm-agent-php/src/bootstrap_php_part.php
elastic_apm.server_url=http://<redacted>:8200
elastic_apm.service_name="Nextcloud"
Description of the problem including expected versus actual behavior. Please include screenshots (if relevant):
APM runs fine for a few minutes, then an error sequence appears repeatedly in logs (see below).
Configuration is Nextcloud running on Apache 2 with PHP 7.4 FPM. Stack otherwise runs fine.
Steps to reproduce:
- add agent extension to php.ini file
- restart php7.4-fpm service
- wait a few minutes, then exercise website
Errors in browser console (if relevant): none
Provide logs and/or server output (if relevant):
