Description
Files in root://dtn-eic.jlab.org//volatile/eic/EPIC/EVGEN/BACKGROUNDS/BEAMGAS/proton/pythia8.306-1.0/100GeV/ are not statistically independent. Several files have identical content
- run001, run002, run004 (3 files)
- run006, run007
- run013, run014
- run019, run020
- run025, run028
- run038, run039
- run046, run048
- run055, run056
- run079, run080
- run084, run085
- run086, run088
- run090, run092
Perhaps, if PRNG was initialized with a second precision timer, several jobs could have started on the same second.

Research direction
Start by comparing the listed run files under root://dtn-eic.jlab.org//volatile/eic/EPIC/EVGEN/BACKGROUNDS/BEAMGAS/proton/pythia8.306-1.0/100GeV/ and inspect the generation setup that produced them. Verify whether repeated outputs share a second-level PRNG seed; done means the affected samples are independently generated and the duplicate-content check no longer finds these pairs.
