ArcGIS 10.2. I am having a problem with ArcMap or ArcCatalog crashing when I try to validate topology. Only one rule - must not overlap, 139 features,2.4 MB. I have tried zooming in to just a few features, as well as really zooming in to an area where I suspect there is overlap. Have tried network location, C drive, network licenses, checkout licenses, creating new GDBs and new topology. I have also tried a repair geometry, then running the topology check. I will try to find a another computer - maybe there is something "wrong" with the one I am using. This also happened in 10.0 SP4, but seemed more random. Usually validate worked, but sometimes decided to crash consistently for several days
