When a Web browser attempting to connect to a site hosted by 4DBK receives this error, you should first make sure that enough memory is allocated to 4DBK to process further requests. By default, critical memory allocated for the 4DBK Web server is 2mb (total memory default allocation is around 40 Mb).

To increase the critical memory allocated to 4DBK's Web server:
1- Select Preferences from the File menu.
2- Click the Advanced Tab control.
3- Set the new value using the ruler "Critical memory for the Web server".
4- Click OK to save the changes.
