index.php/fa/30671/0/The Eclipse always hangs and then throws a "Unhandled event loop exception" when I share a project (Team->Share project). There is outOfMemory in the .log, I tried to given larger memory but that did not work.

As I said on your other post on the JDT forum, it's best to ask on an IBM forum specific to the technology you're using.
