How to restart a patch auto resolve?

While performing a large reverse of a changeset in a stream with 20,000 files to undo, the eclipse client had an out of heap crash.  Upon increasing the heap size and going back in to the eclipse client, the patch change was no longer listed under pending changes.  I assume this was interrupted and must be restarted, but there are no changes pending either way between the workspace to the stream either.  It seems as though the reverse a server side operation and really it would be completing on its own, eventually turning in to an incoming change to the workspace.  Can someone tell me if I need to restart an auto resolve of a patch, created by reversing a change set, and if so how?
