Sorry for not explaining more fully. The program is located at
http://limewire.org/debug/condi.jar - it's a stripped-down version of LimeWire with no GUI that just connects to the network, issues some searches for random dictionary words, and logs some information about each connection, like how long it stays connected to each ultrapeer, the number of search results received, and the number of incoming searches. The program uses less memory than LimeWire and a minimal amount of CPU and bandwidth. It runs for an hour in the background; while it's running you should be able to see an icon in the system tray that shows a lime with a question mark in front of it. When the program exits it will leave behind a file called condi.log - please email the file to mrogers at limewire dot com and I'll try to determine what's wrong with your connection. No personal or private information will be written to the log file - you can open it with a text editor before sending it if you're curious about what's being logged.
Cheers,
Michael
