It seems to be somehow connected to PET/SPECT. It doesn't occur in Radiotherapy simulations. Our workaround, change the seed manually and restart. Usually this works. A more permanent solution would be greatly appreciated, though.

This seems to be related to the random engine. From time to time it seems that the random engine (in auto mode) gets a wrong seed (a negative one for example) and get stuck there. I tried providing my own seed from a file, and even though the seed seems to be taken into account, the result from the simulation (the dat files) are always the same (a diff command yields no difference). This can be repeated using any random engine provided.
