An exception occurred while processing a request for :

iView : pcd:portal_content/every_user/general/defaultDesktop/frameworkPages/frameworkpage/com.sap.portal.toolAreaiView

Component Name : com.sap.portal.navigation.toolarea.default

The exception was logged. Inform your system administrator..

Exception id: 11:22_09/09/07_0114_319630050

See the details for the exception ID in the log file

In the log file the cause for error was displayed as:

Caused by: java.lang.OutOfMemoryError

Pls reply to this. its urgent.
