Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
        - I installed nagios on a fresh debian12 vm, and everything seems to work fine. But when I'm checking the nagios logfile, I find multiple (~50/sec) entries, which report a Host UP that never went up.
   * What exactly did you do (or not do) that was effective (or
     ineffective)?
        - I tryied to install it on new VMs multiple times, but the result stays the same. The strange thing it works perfect on the same Hardware when I use 'debian11'. I even tryied to install it on new servers, because I thougt maybe the old ones are not powerfull enaugh(we have ~10000 Hosts and services on this instance)
   * What was the outcome of this action?
        - Nothing, I was not able to solve the probelm.
   * What outcome did you expect instead?
        - I thougt it would work fine, as with debain11, because the new servers are much more powerfull.
