In our Flowable 7.2.0 CMMN Case Model we have a Timer Event Listener set to cycle at R168/PT1H. Basically every hour for 7 days. It works correctly, firing once an hour for the first few days (it appears to be in the range of the 80th-90th cycle this happens for the current solution, but we have seen it in tests every 5 minutes with fewer), and then fires the remaining times in immediate succession completing the rest of the 168 in a matter of minutes.
Has anyone seen this? I have seen posts about it not firing, and even firing slowly, from quite a while ago, but nothing about it essentially losing the interval.
