White box failing due to FileExistsError

[assaf-speedb]

The white box crash test is failing in several branches.
According to @isaac-io - it is related to a debug code we added.
The command I run:

make clean; time make db_stress -j16; time make whitebox_crash_test

The crash command that fails (example):
