I thought so. Thanks for confirming!
That is very strange, though, as I am not aware of any mayor changes in any of the qvw's.
I guess it was a one-off malfunction as it did not show up again since. Let's see what it looks like on Monday.
Unfortunately, we keep only the very last log_file of every Qlikview_app on the server (for reasons of memory_space), so unless I can "catch the culprit redhanded", there is no chance to decide just which log_file I have to look into - we have about 20 qvw_files scheduled for automated reload - tendency on_the_rise.
