Solution

This process is triggered if the 'Web-vulnerability' scan is going on.

It is recommended that this scan is turned off during production hours.

Here is the CLI output if this process is running:

diagnose system top

Here is a screenshot (center).

 

If this process is consuming the CPU and stopping it does not reduce the CPU, it needs to be killed manually.

Below are the steps from CLI to kill this process:

• Get the process-id of WVSD from 'diag sys top command'.
• Kill the process from the CLI.

diag sys kill 11  2338
