No search results after ~3hrs connection
 

First of all, I like limewire, limewire tastes good, smells good, looks good and feels good.

After approximately 1-3hrs connectivity search results stop to appear, if I disconnect and reconnect the results appear again, even for the simpliest queries no results are shown. I've even tried starting a new limewireprocess when the old one doesn't return results and the new one does(for the "same" query).

Versions:
2.04 and 1.8c

I have a guess that it might be because of some firewall or something.
Any ideas?
