FB4 constantly crashes

[Guest]

Between these three exceptions (with FB3 and FB4) I've had a really hard time getting any work done.  Are people seeing these and

have fixes?  FB4 crashes almost every other clean/build cycle for me.

I've used many different permutations of values for Xmx and XX:MaxPermSize to no avail.  Currently they are set at

-clean
-nl
en_US
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.0.200.v20090519
-vmargs
-Xms150m
-Xmx1000m
-XX:MaxPermSize=168m
-XX:PermSize=96m
-Xss256k
-Djava.net.preferIPv4Stack=true

Hi

My settings are (these are install defaults):

eclipse.vmargs=-Xms256m

-Xmx512m

-XX:MaxPermSize=256m

-XX:PermSize=64m

Good luck

Hi,

Are you using Flash Builder 4 release?

Is it a Stand Alone or Plugin Configuration?

Does this happen only on the current system or across other systems too?

Thanks,

Balaji

I'm using FB4, not the plug-in.  I was able to reduce the number of crashes by separating my library projects from my application projects.

I'm not sure what you mean by 'across other systems'.  If you mean operating system, I've been running on Windows 7 using java jdk 1.6.0_18-b07

Just before I replied, I got another (different) crash

-clean
-nl
en_US
-startup
plugins/org.eclipse.equinox.launcher_1.0.201.R35x_v20090715.jar
--launcher.library

-vmargs

-XX:MaxPermSize=256m
-XX:PermSize=96m
-Djava.net.preferIPv4Stack=true
-Dorg.eclipse.equinox.p2.reconciler.dropins.directory=dropins

I've had similar problems with different values for the settings...

Some memory leaks have been fixed in the upcoming version of Flex SDK compiler. I believe those will resolve the issues you are facing.

For now, I'd suggest the following for large projects like yours which runs into out of memory errors frequently:

* Keep the amount of projects open at one point to a bare minimum. You can use absolute path to the SWC in the bin directory instead of the project in Properties -> Flex Build Path.

* Move embedded assets into a runtime CSS file if possible. Runtime CSS files are compiled separately and only when you change the CSS file.
