Hi, The Event Admin handler test suite has a test case sending an event storm and checking the reception of all of them (in async mode). In synchronization mode, it might be possible that the event handlers become blacklisted (if they don't return 'quickly').
So first, check if your handler are not blacklisted (it is possible to disable this event admin feature). Then try the asynchronous mode. If you see a strange behavior inside the handler, feel free to open a jira issue. We will look into it.
