Node.js is consuming a high amount of CPU.
When looking the ports bound with netstat -anob, it confirms that the node.js process using that high amount of CPU is Data Profiling Service (Port 4949).
Environments:
Resolution:
This can be due to a user uploading an xlsx file containing a sheet with a high number of rows and several columns in it.
When Qlik Sense loads such a file, it analyzes that all columns contain data, and so it will load and analyze a couple thousand rows * columns, which can cause the Data Profiling Service to hang and preventing it to be used by other users.
It can usually be fixed by editing the load script.
