It's not easy to repro. It usually takes a day or two of uptime before the failure. Most of the time it happens when navigating the Internet Radio lists using the Find a City menu item, but it has also happened when moving between favorites. It has not happened yet when I go through the Touch UI, it always happens when using the SB Radio pointed to the Touch server.

When I Putty into the Touch and do a top, I see the slimserver.pl process at 80%. I'm assuming this is a good indicator that it is hung and no longer processing requests from the SB Radio.

Here's a snippet of the log (/var/logs/messages) at the time of the hang. Is there any additional info I can gather to help with the resolution of this issue? I've looked for memory/processor diagnostics but haven't been able to find any.
