> Job history file is not flushed correctly because isTimerActive flag is not 
> set true when flushTimerTask is scheduled.
> It looks like we should set isTimerActive to true when flushTimerTask is 
> scheduled. Otherwise if a new qualified event comes before the current flush 
> timer is expired,  flushTimerTask will be canceled and rescheduled.
> Also I didn't find any code which set isTimerActive flag to true, So 
> isTimerActive is useless in current code.
