Errors in Sitecore Cleanup Agent

  • By default, Sitecore Cleanup Agent is automatically executed every 6 hours to maintain the file system by removing outdated Sitecore files, such as obsolete media cache or log files. When having insufficient permissions to remove the necessary files, Sitecore Cleanup Agent will fail with an error.
