Hello,

since 24 of June 2024 we daily get an error message that the task \tool_analytics\task\predict_models fails.
A week bevor we updated our moodle to version Moodle 4.4.1+ (Build: 20240614)
Except for the error messages we don't see any problems.

Two other Moodle instances with the same moodle version don't have this problem.

The error log starts with this:

Execute scheduled task: Modelle vorhersagen (tool_analytics\task\predict_models)
... started 01:10:16. Current memory use 28.2 MB.
Debugging increased temporarily due to faildelay of 86400

and ends with
