Hi.. I'm running aMule 2.1.3 on Kubuntu v6.06. I also have this problem and I don't think its a "fake server" because this happens after a few successful searches.
Usually that search progress bar would move across, but it doesn't even start to move when this problem is happening. Whenever I restart aMule it would work again but then stops after a few searches again.
Is there anything that can be done about this?
