Action

Proceed as follows:

  1. Analyze the memory consumption and run netstat (TCP sockets in illegal state). If you encounter any issues, restart the QPS as connections (that is, web sockets to the QES) are disposed by the Qlik Sense Proxy Service (QPS).
  2. If the problem persists, check that the QES is up and running.
  3. Contact Qlik support.
