Actions: Immediately sending to multiple recipients with escalations enabled broken.

[Surge]

I've run into an undocumented feature/bug in Zabbix 1.8.3

I have an action with escalations enabled.
I want to notify two user groups immediately in steps 1 to 2.
There is no option to add multiple groups to a single "action operation" so I set up the action operations like so:

1 - 2 Send message to Group "Network administrators" Default Immediately
1 - 2 Send message to Group "Telematics network administrators" Default Immediately
3 Send message to Group "IT Infrastructure manager" Default 01:00:00

The problem is that only the "Network administrators" are notified and then the "IT Infrastructure manager" is notified an hour later.
The "Telematics network administrators" action operation never runs.

The only work arounds are to split the notifications up into two actions (which makes things more cluttered) or to delay the notification to the second user group by using step 3 and onwards.

I've seen this too. Our actions are setup differently so I don't run into this all that often.

As a test, change the first two actions to 2-3 or 2-0 instead of 1-2 (you will want to bring your escalation down a little bit too for testing). If that works, I'd open a bug up on the support site and then until it gets fixed, change the escalation to be a small number, then bump up the 3rd action to something like 10-0 or whatever value gets you to an hour.
