The show_age_threshold can be set to -1 to disable the feature that updates notifications with their age.
In this scenario the
queues_get_next_datachange
may return -1 to indicate that there is no next wakeup time (e.g. when there are permanent / critical notifications).The code that calls
queues_get_next_datachange
should take this scenario into account and not schedule another timeout if -1 is returned.Addresses #1163.
