Escalation Mails not correctly working

[Firewire2002]

Hello,

I have Escalations with actions with a 15 minutes delay configured.
If a host goes down, the Action would be 15 minutes later performed. Thats ok.
But if the host comes back within the 15 minutes the mail with status "PROBLEM" is also send and the "OK" message some seconds after that.

I tried the following configurations of actions:

• one Action for problem and recovery message with delay 900 seconds and action from step 2 to step 2)
• one Action for problem and recovery message with action condition "trigger.value=problem", delay 900 seconds and action from step 2 to step 2)
• two separate actions for problem and ok message with action condition "trigger.value=problem", delay 900 seconds and action from step 2 to step 2)

How can I solve this problem?

Regards,
Fire
