I am running a higher traffic site and in times where we have more traffic, we get errors when archiving reports. The error goes away sometimes but comes again once there is a bit more traffic again. We can’t raise the memory_limit without a server upgrade.
Interestingly, the dashboard looks OK, it shows users, events etc.
So I am worried about the impact this actually has, are the statistics incomplete? What is the expected impact of this error message?

INFO [2022-05-09 07:36:32] 15650 Error: Got invalid response from API request: ?module=API&method=CoreAdminHome.archiveReports&idSite=1&period=day&date=2022-05-08&format=json&trigger=archivephp. The response was empty. This usually means a server error. A solution to this error is generally to increase the value of 'memory_limit' in your php.ini file. For more information and the error message please check in your PHP CLI error log file. As this core:archive command triggers PHP processes over the CLI, you can find where PHP CLI logs are stored by running this command: php -i | grep error_log
