What are the possible causes of a Timer Thread RTE when all of the timers content are poll-groups?
In this case serial polling is done and a condition is defined on the timer.
Normally the timer will move the poll-groups on the execution queue that is running in the protocol thread. In case executing the group would take too long I would expect a Protocol Thread RTE, not a Timer Thread RTE. So when can this occur?
@João, Indeed the TimerThread waits to redo the entire time cycle until the last group in executed by the ProtocolThread. If the execution of that last group is delayed, then the TimerThread will every minute update the watchdog, so no RTE should be created for the TimerThread.
Unless the thread effectively dropped out, I think we'll need a dump of the process to be able to explain this.
