Hi Martin, I’m a bit confused now… is there really a bug in 2.4.0p23 and we should wait for p24 or is it only related to version 2.3.0p43 (that’s what the werk mention)?

Thanks!

Sorry, too many releases this week and next week planned… Mixed 2.3 and 2.4 up…
Nothing to see for 2.4 :slight_smile: Hopefully. My comment was related to 2.3.0p43

It`s just a hotfix for big devices like here:

Error when rescan devices - Troubleshooting - Checkmk Forum

or

Service Discovery fails with “failed to fetch state [500]: INTERNAL SERVER ERROR. Retrying in 1 second” - Troubleshooting - Checkmk Forum
