Hi everyone,
On our institution, the ajax service.php seems to be failing randomly, specificly when are being requested these two json in the Overview page: core_course_get_enrolled_courses_by_timeline_classification and core_calendar_get_calendar_monthly_view.
The error thrown is the typical "undefined" error window, here I attach an example:
Server response is incomplete, the json stopped being printed in middle of a base64 image:

More courses and data is missing in this json. But if I just refresh the page it works correctly.
Any idea about what could be going on here?
Moodle version we are using: 3.7.1 (Build: 20190708)
