Older discussion about restarting below (uses test server paths)
To restart your friendly neighborhood drupal bot when it no longer responds to commands, first kill the zombie bot for real.
When you kill it, the bot disappears from the channels so you don't have to kick it out, and the re-started bot will be able to claim its proper name.
