Eclipse not responding

Question

Was working fine yesterday, overnight Windows 7 rebooted, now Eclipse won't finish loading - spinner displayed with "Eclipse SDK (Not Responding)" Dialog "User Operation is Waiting" for "Building workspace" to complete. Android SDK Content Loader remains at 0% I have tried:

• eclipse - clean delete C:\Program Files\eclipse\configuration.settings\org.eclipse.ui.ide.prefs

Here's the top of the Log file, which I cannot interpret. Any help would be gratefully received.

In the .metadata.plugins directory, search for files with "snap" in the name (e.g. .snap, .markers.snap, .syncinfo.snap, etc.). When I stopped Eclipse and deleted all of these files, Eclipse then started normally on restart.
