Redmine

I've installed Redmine 0.7 on a FreeBSD 6.2 server, and I'm having a really hard time keeping things running continuously. With WEBrick, it runs okay for a while, and then just stops answering requests. The ruby process needs a kill -9 and a restart to get it going again. I've now switched to FastCGI under Apache, but it also craps out:

I'd like to give Mongrel a try, but as I'm a newbie to Rails stuff, it's not clear to me how to load the Rails app using Mongrel instead of WEBrick. Has anyone tried doing this?

Thanks,
