Hi,

When I meet this one on a dev environment, I simply:

* shut down storm
* delete the storm local state folder (/home/elsztok/storm_tmp/ in your
configuration)
* restart storm

This basically resets all local state of nimbus and ui as I understand it.
I'd be glad to hear if there was a cleaner approach.
