I use Eclipse Java EE IDE Kepler for Web Developers with pydev.
The first instance of Eclipse hangs on startup while loading a workspace.
If i start eclipse again, a coexist second instance of eclipse works fine.
I used different workspaces, the problem is independent from the used workspace.

I think that the best approach would be identifying the stack you have when it hangs and then reporting a bug (probably in Eclipse: https://bugs.eclipse.org/ but it may be in PyDev: https://sw-brainwy.rhcloud.com/tracker/PyDev depending on the trace).
On http://pydev.org/faq.html#PyDevFAQ-HowdoIReportaBUG%3F there's info on how to get information on a halting condition.
