I’m running Nagios 3.2.3 (but saw this in 3.2.1 as well) and have a very annoying thing happening. I can ack an alert, and after a few days or so the ack disappears and I get alerted again. Is there a time-limit to acks? It doesn’t matter if I mark the ack as sticky or with a persistent comment. If I view the service, the comment from the ack is still there.
Any ideas why this is happening?
