Unpredictable behaviour in debug mode - multi process application

I'm working on an application which spawns multiple processes which works as expected when running normally however in debug mode, it behaves erratically at best. Sometimes not all processes spawn, other times I see '[Errno 48] Address already in use' (even after killing all instances of Python). The application often behaves differently then usual and I think this is due to the debugger not coping with the multiple processes that it has to attach to. Is there anything that can be done about this?
