On your QlikView server, navigate to C:\Program Files\QlikView\Management Service. Open the file "QVManagementService.exe.config" in a text editor like notepad or notepad++. Search for a line like this:
<add key="MaxLogRecords" value="1000"/>
Change the value 1000 into something lower and restart the Management service. Then try again.
