I am on 4.8.1. I have no problems memory wise. Other applications work, but they won't connect to the internet. Say I have 10 files downloading (50mb total bandwidth), no files uploading, and maybe 90 files waiting for sources or one of those messages. In situations like this I am unable to browse the web, for example.

I still have 200+mb bandwitdh and I can still browse other hosts' files but I can't use any other applications to connect to the internet.

This is mac os X 10.2.8, on a 500mhz laptop with 1gig ram.
