i noticed that rerunning the same job twice gave difference in some jet tag monitoring histograms. i think the reason is the incomplete resetting in:

https://svnweb.cern.ch/trac/atlasoff/browser/physicsanalysis/jettagging/jettagmonitoring/trunk/jettagmonitoring/runsummary.h#l107

for instance jfcnn_pos and jfcnn_neg are not reset here, and thus never initialised (there might be more of course so please doublecheck all variables).

cheers,
