Why does RAD 8 consistently hang on startup?

I am experiencing a problem where Rational Application Developer 8 consistently hangs indefinitely on startup. I've only been able to find a partial solution: I can get RAD to start up if I delete the <n>.tree file in the workspace's .metadata.plugins\org.eclipse.core.resources.root directory. Once started however, all projects must be re-imported.

What I can't seem to solve is the underlying issue -- the issue recurs after every shutdown of RAD, and I'm having to delete the .tree开发者_如何学JAVA file and re-import the projects each time I start the app. Shutting down RAD normally does not prevent the problem from recurring; neither does removing all projects and cycling RAD with no projects (problems start again immediately the first time RAD is shut down with projects still imported). I've even created a new workspace from scratch, but it didn't help either.

I'm at a loss. If anyone has experienced this, any insight would be greatly appreciated.

I am currently experiencing the same problem with an older version of RAD and haven't found a working solution yet so far, but you might get some pointers from here: How do I prevent Eclipse from hanging on startup?

At any rate, you can check the ./metadata/.log file in your workspace for useful information about where exactly it hangs.

There are many background process starts when Eclipse or RAD starts. You can disable the background process which is not required. These can be found under Window->Preferences->General->Startup and Shutdown.

Delete Temp files under /tmp folder and restart RAD...

Worked for me...
