This was something I did look in to. You simply change the setting as described above. i.e.
However some months ago we had to change the setting 'Server...' to 'Client initiates...' because of some session termination issues we were having.
The Qlikview setting for "Refresh Mode when document is Updated on Server" was set to "Client initiates refresh. If old data not kept on server or client too old, session will be disconnected" , this is incorrect as it clashes with the "Allow only one copy in Memory" parameter of the Qlikview server control Panel. "Server performs refresh automatically without any client action".
The statement about "A setting that may cause this..." was from Qlik (not myself) so I would take it with a large dose of salt.
Thx a million. I changed the settings for the application we faced this issue with. Since we had up to five errors of that type a day we shall rather quickly see results (or rather not see anything at all, since the error vanishes).
I did try changing the server settings, but the error still came up qhen I tried to draw a PieChart with multiple expressions. I tried changing some expressions, but the result was always the same. The application closes down and sometimes I get the following error. If I change the chart to use a Mekko chart, it renders just fine.
Add type CT to the mix. Occurred while opening a 250GB+ file, and while I already had 3 files open, one of which was also that size (and indeed a copy of the same file, but about a month old and with a different filename). Text was simply "Internal inconsistency Type CT" - nothing more. Can't screenshot because the app has since quit.
