capistrano not restarting, stopping but update is working

I recently changed machines, and had a few rough spots updating Rails. The server itself stayed as it was. Everything seemed to be fine, but not capistrano. When I make changes and update SVN, running

cap deploy

the correct new version of the repository is placed on the server. The logging in the terminal running capistrano shows nothing out of the ordinary, but evidently no restart actually takes place because the server continues to run. Running

cap deploy:restart

Produces

    servers: ["www.urbanisti.ca"]
    [www.urbanisti.ca] executing command
    command finished

But no evident change takes place. What might be going on? The Mongrel log on the server shows no changes whatever: it's still running the older version that predates the update.

The problem would seem to be in your custom (or, at least non-built-in) restart task. The task accelerator:smf_restart, and associated smf_stop and smf_start tasks, that are being called are not part of the standard Capistrano suite. Did you write those tasks yourself or are they from a Capistrano extension? If so, what extension?

If you can post a link to that extension, or post your Capfile if you wrote them youself, that would help people figuring out more specifically what's going wrong.
