Smarty Name Conflicts

Everyone, When I run a cronjob that executes php with smarty in the shell (for html email reporting) it creates a file folder in the templates_c folder with the user that executes the shell (which is not "nobody"). Later, when another template is compiled by an end user executing a file through the web(done under apache default user "nobody"), there is an error writing to the directory that was created from the cron job execution from earlier. Does anyone know why the directories are named the same even though they are different tpl files? Aside from changing the folders to 777 when they are created (my sys admin didn't like that option), is there any other workaround? I am using Smarty with Apache on a FreeBSD Unix system. Thanks, Chris Stauffer
