Symptoms

The "Mgmt" memory usage as seen on the BUI status screen is increasing when looking at Analytics data older than a few hours.

This figure is describing the amount of kernel memory the appliance management process, AKD, is consuming.

The process is currently a 32-bit process, so the theoretical max size for this process is 4 GB, typically the process may run into various memory allocation errors when reaching ~3GB in size.
