Hello, Occasionally when I run a report it will just end half way through a report and will do it again and again 50% of the time on the same script, there are no errors in my code and it runs just fine. Qlikview yields no clues as to why it does this, it just comes up with the message you get if you force a script to stop executing mid way.
The first thing would be to turn on the script logging if it's not on already (Settings > Document Properties > Generate Logfile). This will hopefully tell you what's going on.
Since you're saying that the application is just freezing mid reload with no error messages etc. until you try to stop the execution, it sounds to me like you might be building a large synthetic key, or joining some tables without related fields by mistake.. some kind of resource intensive operation that exhausts the memory on the machine.
