### Description
Hi, everyone. I want to debug backend of Doris by using VSCODE. However, I tried the [official doc](https://doris.apache.org/community/developer-guide/be-vscode-dev/), I still can't lauch the GDB to debug. Could I get some help?
The below is my lauch.json

Thanks a lot for your kind help! It seems the machine setting is a reason.

Could you please tell me your dev environment, like size of RAM and number of cores? I doubt that it can't run because of the machine(for me, it's 4c8g ubuntu) :)

You're welcome. Try again with a new machine.

@koarz Thanks again for your help! I used my local machine with LLDB's `attach` mode and it can debug successfully!

For this issue, it seems that the doc mentioned the machine request is at least ***10c16g*** to run debugger successfully.

@codeDing18 Hi, thanks for your suggestion! I compiled the BE by myself. The problem was handled after I changed another machine. ;)

But it looks like the documentation's PALO_HOME hasn't been changed to DORIS_HOME, so I reckon I should need to use DORIS_HOME instead of PALO_HOME now

Thanks for your help! I will try using `attach` instead of `launch` to debug.

hi,Is your BE compiled by yourself(`BUILD_TYPE=Debug sh build.sh`) or is it an official package?

I haven't used Launch debugging, but attach debugging doris is very convenient, maybe you can try to use lldb's attach debugging
here is my config

Simply select the be process that has been started and you're done!

Yes, I noticed this problem and I changed to `DORIS_HOME`, however it still did not work ;)

My machine is 16c16g, despite that sometimes there's not enough RAM, 4c8g doesn't look like it's up to the minimum configuration
