Care to share the process model? From what I can tell, It looks like you may have a process that is calling itself in a subprocess.

Mike Schmitt · Answer

As the error message says: the maximum "depth" of subprocess calls (from the top-most parent) is 100. The only time I've run into this myself was when I was using a system of recursively invoking new instances of the original top-level process to avoid having to do too much looping in the design (which, to be fair, worked well until one particular instance pushed the depth over 100).

Mathieu Drouin · Answer

Well that's pretty much your issue right there. You have a recursive loop. Technically, you can only loop 100 times using this method.

fxzrqjzztrmy said: how is process depth counted 
 Pretty easily - the first ("top") process is level 1, the first subprocess call is level 2, the next subprocess called by that one is 3, etc.
