I have tried this but it failed to help. Flex Builder running slow or hang, or get "out of Memory" message Flex Builder will consuming memory over times, especially when you have a lot of projects created in FB. You can monitor the memory usage of FB from windows task manager. Look at the javaw.exe process, the above mentioned problems usually happens when the memory usage of javaw.exe is too height. You can close and restart the FB to clean up the memory.
By default, FB set the heap size for Java virtual machine in FlexBuilder.ini as following: -vmargs -Xms256M -Xmx512M If you exceed the maximum value, "OutOfMemory" errors can occur. If your system has more total memory available, then you can increase the maximum heap size value. The rule of thumb used to be set the maximum heap size no more than half of the total memory available. However, with the new features and settings in the newer version of JDK, there are more factors you need to consider when deciding what is the best maximum heap size you can use. You can consult articles about heap size online. To change the heap size settings, you can modify them in FlexBuilder.ini under the FB root directory. If you start FB by command line (or using Eclipse), then you can change them by command line (or FB2 shortcut) such as "C:\Program Files\Adobe\Flex Builder 2 Beta 1\FlexBuilder.exe" -vmargs -Xms256M -Xmx512M 7. NullPointer Exception when open FB If you leave some files open when you close FB and restart FB later, by default FB will open the files you previously opened. If one of those opened file has been deleted already at this time, then FB will throw NullPointer exception. All you need to do to get rid of the exception is to close that file. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Wade Arnold Sent: Tuesday, May 09, 2006 11:56 AM To: Flashcoders@chattyfig.figleaf.com Subject: [Flashcoders] Flex 2.0 Heap issue Hey All, I am seeing the following error right now on FLEX "An out of memory error has occurred.

Any help would be greatly appreciated.
