Rick,
You are likely running up against the OS hard limit on processes pr userid. This could happen if your code spawns child-processes, and doesn't tear them down appropriately, or because Xcode doesn't terminate the processes corresponding to your project runs correctly when you stop them in the UI (among other reasons).
You can determine the current settings with sysctl:
sysctl -a | grep maxproc
Compare this to the number of running processes for your user with ps:
ps aux | grep <rick-userid> | wc -l
Offending processes will be labelled as state 'Z':
ps aux | grep <rick-userid>
