As Mark has mentioned, you don't want to use -CURRENT for anything production-oriented. While 7-CURRENT has been a remarkably unbumpy ride, especially given the scope of the changes made (ZFS, SMP scalability, etc), I wouldn't run any production services on it until it becomes 7-STABLE later this year. However, if you have a high volume workload that you want to work really well with 7.x, and you can do testing, now would be a really good time to start doing that. Almost all major feature changes are now present in the 7-CURRENT branch, so the next four months are all about getting it into shape for the 7.0 release. Even if it panics on the first day you run a test workload against it, submit a bug report and keep with it until it runs perfectly. :-) The way development branches become stable branches is that people who care about making it happen test the new release until they're happy with it, reporting bugs, fixing bugs, etc, so any help you can provide would be greatly appreciated!
