The freezes I encounter are usually either due to disk i/o (especially memory swapping) or hardware drivers. I guess the latter can be excluded, so you should monitor the memory exhaustion (e.g. use watch -n 0.5 free -m). If this is the problem, you might try to disable swap (sudo swapoff -a), so the compilation is killed when the physical memory is full.

Edit:

I am not sure whether catkin_make_isolated automatically parallelizes. If so, you might want to disable that (maybe append "-j1"?).

If it is the memory problem and disabling parallelization doesn't help, try to lower the complexity of the compilation of the problematic files.

• compile without -g flag (in CMake, set the CMAKE_BUILD_TYPE to Release)
• reduce optimization (this will make it slower) by explicitly using -Og or even -O0

Otherwise, getting more RAM is usually an option.

The above are just ideas from the top of my head. Make sure it is the memory swapping problem first.
