Checkmk 2.3.0p43 updated an internal dependency which introduced a limit on the amount of data the backend can handle per request.

This fix restores the original behavior eliminating some 500 error responses that users may have encountered.

These errors affected operations such as saving large forms and executing service discovery with a large number of services. After this update, these operations will complete successfully without requiring any user action.
