Hi,
in our setup (2 masters, both with notification features enabled) a notification object with interval = 0 will send out more than one notification:

I don't understand why this happens even with interval = 0:

  • Category set to Notifications

This is most likely a duplicate of #11562.

  • Subject changed from notification interval = 0 not honored to notification interval = 0 not honoured in HA clusters
  • Target Version set to 2.5.0

Left node feels responsible for sending the notification first, then you'll restart/stop the left node. Then the right node is responsible for the notification object. It does not get the last_problem_notification timestamp synced (#11562) and will therefore fire its first local notification. The user gets 2 notifications and thinks that interval = 0 does not work. Apparently it is the missing cluster exchange of notification messages - each node normally calculates the notification times on their own.
