Symptoms

The appliance kit daemon (akd) can grow very large and can run out of memory causing the Browser User Interface (BUI) and CLI to be slow or to hang complete.  Log files (only found in bundles) may show messages about out of memory or resource unavailable. This document addresses large anonymous memory mappings within the akd process. The large akd memory usage will not show up in the analytics dataset for heap memory, however, the process size as show by ps or prstat will show a size greater than 7 GB. 

Other symptoms include:

  1. REST or CLI access may fail.
  2. Cluster link may show as down from the other head of the cluster.
  3. Listing the hardware components in the BUI or CLI may hang.
  4. Unable to create new analytics datasets or unable to access analytics.
