High CPU usage on Flash Builder 4.5

[Ch63]

Hi

I’s experiencing serious high CUP usage when working with Flash Builder 4.5.

It happens when I start editing a relatively large .as file (~700 lines of code). Utilization then goes up to 50% and stays in this condition forever. This makes editing and debugging impossible – everything works very slowly including my computer.  Once you close the edited file (which is the only file in editor), utilization is back to normal.

Some more details:

• I have two projects in my workspace. One is closed. I cannot share the project.
• Flex SDK 4.5.1 (upgraded lately)
• Working on Windows XP Professional SP3.  4GB RAM.
• Workspace-log is attached

I tried the following

• Reinstalling Flash Builder – no change
• Uninstall SVN subclipe version that I installed as described here - http://www.flashmagazine.com/tutorials/detail/setting_up_subversion_with_adobe_flash_builder_4/ - no change
• Network monitor is disabled (this is a standard version of FB)
• Quit FB, open it and just load the .as file without debugging or launching any application – same problem.
• Edit FlashBuilder.ini and eclipse.ini and change the values to -Xms512m -Xmx768m – same problem
• Reinstalled FB for the second time and just loaded the same files as before – same issue.

Needless to say it is very problematic as I’m disabled from working for several days already. 

Need your prompt support.

Thanks, Charlie

I posted this very problem a few days ago and have yet to receive a response: http://forums.adobe.com/thread/915515

Hi

I installed an earlier version of FB 4.5 without help. I also tried new work space, new project sources etc - no help.

I suspect it has to do with some collision with internal resources.

Questions to the Adobe team

- How can I inspect where the FB.exe is looping?

- How can I inspect the interaction between FB and its Java VM?

Thanks

I have also noticed that during this time period, for me at least, the memory usage of FlashBuilder.exe increases at a constant rate while the file is open, even if I am not interacting with Flash Builder. At some point Flash builder becomes very sluggish to respond, but if I close the editor with that large file, everything goes back to normal.

Hi,

I rencently had the same kind of troubles (FB hanging when opening a file).

The solution for me was:

     * Disable the Design Mode view ( Menu Window -> Enable Design Mode)

     * Restart Flash Builder

It's worth giving it a try.

You sir, are a gentleman and a scholar. That fixed it! I had a pretty strong feeling it was design mode, but I couldn't figure out how to turn the blasted thing off. I was expecting it to be in the preferences somewhere.

Thanks a lot.

I was hoping this will solve my problem but apparently, my FB is already running in design mode disabled.
