Subject: [PATCH] Fix: Increase Stack size

Low stack size could result in a stack overflow exception if traversing
very highly nested directories.

This makes core-dumps less likely but will not completely remove the
risk

example for creating directories:
mkdir -p $(for i in {1..5000}; do echo -n "qwe/"; done)
