CET  pre-eventsModule run order problem found: 
unpackCastorDigis consumes rawDataCollector, rawDataCollector consumes l1GtPack, l1GtPack consumes simGtDigis, simGtDigis after unpackCastorDigis [path L1RePack_step]
Running in the threaded framework would lead to indeterminate results.
Please change order of modules in mentioned Path(s) to avoid 
inconsistent module ordering.
