Notification "queued" and sent at midnight?

We are using Nagios 1.4 ( I know it’s old) and recently we’ve started experiencing that are notifications seem to be sent to a “queue” and released at midnight. My guess is that this has something to do with the log rollover on a daily basis but I’m not sure when I would have accidently set this setting. Does anynoe have any ideas where I could have set this? Any/all assistance is greatly appreciated!!! I’m really getting annoyed getting woke up at midnight with alerts that happend hours ago…

Thanks!

Hm, there were several bugfixes of retention states. I would suggest upgrade to at least highest version of Nagios 2.x
