Flex And IE Out Of Memory Error
So in the past 3 days I have been trying Flex I've had several out of memory errors that crashed my browser. I don't know if it is my operating system, my browser, Flash in general, or Flex, but it sucks. For the record I am using Windows XP Pro, IE 7, Flash 9, and Flex 3. This is what happens: As I develop, I keep hitting save in Flex Builder, waiting for it to recompile in the background, then Alt-tabbing over to IE and whacking F5 to refresh. Well, over the course of 2 or 3 hours of doing this, the memory usage for iexpolore.exe just keeps climbing and climbing as though there is a memory leak or garbage collection isn't happening.
Finally once IE gets close to about 600 to 700 Megs of Ram I hit refresh, and WHAM! First, Flash pops a cute little error box with a stack trace that informs me "Error Code 1000: The system is out of memory." This page on Adobe's site says, "Flash Player needs more memory to compile your code than your system has available. Close some of the applications or processes running on your system."
I don't by that. My machine has 3 Gigs of RAM, and up to 1.5 Gigs will still be free when this happens. I don't think closing any applications or processes is going to fix it. The error consistently happens around 700 Megs, so I think there is some internal limit in IE or something. Once I close the Flash error pop up, the entire IE process (including all the other tabs I had open) crashes hard with the little "Do you want to send Microsoft your bank routing numbers?" pop up that I always click "don't send" on.
Today I am using Firefox. We'll see how that works for a change. Take that Microsoft.

I've running into the same issue. Unfortanutely, I am yet to find a work around/solution. I believe you are correct in asserting the the problem is not solely memory related. Anyhow, here is an exception I am getting:
Error: Error #1000: The system is out of memory.

If you had made any progress with resolving this issue, please, post. Also, is it possible for you to share the source code of the app that causes this to happen?
Thanks in advance.
The app was pretty basic-- just a bunch of panels and charts with a few web service calls on load to retrieve data.
We are also facing this issue. Please suggest us, we debug and found that in our app we are loaidng modules in tabs, and after 5-6 operatons it gives us that out of memory issue.
Please guide us.
