Compilation using make -j freezes the system (discuss.tchncs.de)

Hi, I am building the Linux kernel, with the following make command to enable multi core compilation: make -j. This ends up freezing the system and eventually some applications get killed (I am using KDE). If I pass an argument to -j, then system compiles normally. However, full multi-core compilation is enabled when no argument is specified.

I am on Debian stable, kernel 6.1.0-13-amd64. Is there a way make system do full multi-core compilation without freezing the system?

Without an argument, the -j option will start jobs with no limits - depending on the project, this could be thousands or tens of thousands of processes at once. The kernel will do its best to manage this, but when your interface is competing for cpu resources with 10,000 other cpu-intensive processes, it will appear frozen.
