"Expected within 1000 ms the async HstConfiguration EventListener to have caught up with the InvalidationMonitor#SynchronousOnEventCounter listener counter. However async counter is as '8' and sync counter at '9'. Stop waiting longer."

Solution

The change implemented is as follows:

In case the async and sync listener are not in sync within 1 second, a
warning was logged. However, we cannot know whether this is a persistent
missed async event or a temporal missing event.

For that reason, we for now log an info and only start logging a warn
in case the problem persists longer than 60 seconds
