However memory limits are taken in to account. eZ Publish view cache is generated on demand (as long as pre-view cache is disabled, by default it is), thus as long as you don't access the node the view cache won't be generated. Check error logs to get some info what wrong happened. I bet is was memory limit either you have reached maximum execution time.

Hi there;

I'm using import_data extensions to import objects through csv files. The amount of data I imported in eZ 4.0.1 successfully causes internal server errors in version 4.0.3 (script timeout I suppose).

How can I prevent this? I suppose that it's because of generating cache for new objects? Can it be turned off for the time of import and then re-generated on a cron basis, or manually?
