Previously, the Memory service could report an incorrect memory usage on ArubaOS-CX / HPE Aruba Networking switches, where the summary looked like this:

Total (RAM + Swap): -7.54% - -573 MiB of 7.42 GiB RAM

This happened because these switches already exclude cached memory from the reported usage, while Checkmk subtracted it once more. This has been fixed. These switches now report the correct memory usage automatically, without any configuration.
