Symptoms
The appliance kit daemon (akd) can grow very large and can run out of memory while disk firmware is upgraded if there are many disks to be upgraded. This may cause the Browser User Interface (BUI) and CLI to be slow or to hang completely and may cause disk firmware updates to fail to make progress. Log files (only found in bundles) may show messages about out of memory or resource unavailable. The large akd memory usage will appear in the analytics dataset "dynamic memory usage for application 'mgmt'". This document addresses the issue found while disk firmware was being upgraded shortly after the appliance software was upgraded.
