Were you running as an ultrapeer while that happened?

I think I've found something but it doesn't seem to be related to ethernet downloads but to searching while you are an ultrapeer.

This is what happened: When running LimeWire in ultrapeer mode a search, when I start it, might cause all connections to be dropped. So far it appears to be some weird synchronization problem that keeps connections from being initialized properly after I started a search. Disconnecting LimeWire and connecting after several seconds solves the problem.

I'll be able to tell you more in an hour or so.
