Sorry, I should have explicitly stated that I want to continue to allow users to create objects that would be beneficial to them and not detrimental to the server or any of the other users.
The server documents currently have over 2000 user created objects (excluding bookmarks) and turning off this functionality is not an option.
You could try to set the parameter "Object Calculation Time Limit" to a lower one. The default is 60 seconds but you can define it to 5 seconds or maybe less. Don´t define too lower because if you have complex document objects, they will display the "calculation time exceded" error. Define a number of seconds that allows you to render the well designed objects , but also limit the bad ones to calculate and take all of the system memory.
According to the manual "The Object Calculation Time Limit setting specifies the maximum amount of time the QlikView Server will attempt to calculate a chart object. The time is set in seconds of total CPU time. Note that
total CPU time is not same as elapsed real time on a computer with parallel processing technology".
