    Description

      If timers (here calendar timer) are running longer than scheduled, or the schedule/processing get stuck do to thread or cpu bottleneck, it is possible that the updates for persistence overlap.

      The issue seems that the task(1) try to finish the timer and task(2) is about to start but see the concurrency.
      The DB is updated with the 'old' next timeout, but the internal Timer instance will be updated with the next possible schedule due to a race condition between the two threads updating the object.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
