Keys in xterm keep repeating
 

I have a strange issue where when I open an xterm on my Fedora 8 machine and start typing, a key that I press will start repeating over and over. For instance, when I am typing a command, like "ls -l", it seems that a key will stick and I get the command "lssssssssssssssssssssssssssssssssss" until I hit the Ctrl C key.

I have tried rebooting but this issue keeps happening.

Where should I start troubleshooting this issue?

I have seen this happen when system resources are low.

I know this might sound like an obvious answer, but it could be the 's' key on your keyboard which is at fault.
Try replacing the keyboard and see what happens.

No, it is a random key that will repeat.

I tried setting the key repeat rate to the lowest repeat rate and interval, but the phenomena still occurs.

I was looking at a Ubuntu forum where this was happening, but it didn't appear that there was any particular solution.
