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.
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).
The mainprocess will call itselt as a sub-process at the end, how is process depth counted here? Like other sub-processes are also counted
Well that's pretty much your issue right there. You have a recursive loop. Technically, you can only loop 100 times using this method.

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.
