I am facing a problem since there will be a serious error shutting down ArcMap (tried 10.5 and 10.6 on several systems) any time I run the script. I tried to split the very big feature class in blocks of 500 features to be split. I additionally removed null geometries and fixed geometry (self intersections). Now some blocks are processed well, others not.</P><P></P><P>What else should I try to avoid/debug this annoying error?</P><P>(Sorry, the script might be way too long for a quick overview.)</P><P></P><P>Thanks in advance!</P></BODY></HTML> Mon, 08 Jul 2019 08:46:18 GMT https://community.esri.com/t5/geoprocessing-questions/serious-error-with-working-script-no-clue-why/m-p/396338#M13487 ArtyArt 2019-07-08T08:46:18Z Re: Serious error with working script, no clue why https://community.esri.com/t5/geoprocessing-questions/serious-error-with-working-script-no-clue-why/m-p/396339#M13488 <HTML><HEAD></HEAD><BODY><P>Adjusting some screws, I figured that the "step_value" in line 61 (crucial for the cutting/splitting operation) raises the error.
