Hi Limiting Burp's heap size to 1GB is a rather low amount. Could you try increasing this to 4GB? What is the version of Burp you are using? Are you using Burp with an extension for your second command?

Tried with 4GB options facing the same issue in both commands I am using early adopter version v2021.7.2-8935 Yes for the second command I am using burp with extension loaded

Unfortunately, any issues with the extension will need to be raised with the extension's author, as we are limited in how we can support third-party extensions. For your first command, have you had a look at our instructions for launching Burp from the command line? You can find these here: https://portswigger.net/burp/documentation/desktop/getting-started/launching/command-line This includes the arguments that you can use when launching Burp. As you are launching Burp headlessly, there will not be much output to the command line. This is because the majority of Burp's features rely on the GUI. You can check whether Burp is running by going to http://burpsuite (or 127.0.0.1:8080) in your browser and seeing if you receive the appropriate Burp page.
