I now did some more testing. Apparently in my application only the main random generator is affected. If I use the default engine and set the seed using setTheSeed and a value from urandom and print every engine status in the BeginOfRunAction() only the first engine is different for a couple of runs.
Then I tested to set the seed for every thread independently using G4Random::setTheSeed() in the BeginOfRunAction(). However then the whole simulation ends in strange behaviour with no reasonable output.
I run the simulation in 200 threads and want to perform a couple of independent runs to add up. Is there any option to initialize the random engine in a way to do that in multi-threaded mode?
