Previously, omd could fail to reload the system Apache. This issue occurred in case of a mismatch between the OpenSSL version included in the Checkmk distribution and the OpenSSL version required by the system Apache. As a result, the error /usr/bin/systemctl: /omd/sites/v240/lib/libcrypto.so.3: version OPENSSL_3.4.0 not found would appear in the output of omd.
