It can be a problem if the source of the RSS is unreliable, like off the network, or if you're doing DNS queries against a flaky DNS server. Ruby's interpreter actually stops completely during most DNS queries so if you are using say net/http to connect to a flaky web site you could block the whole show. I'm not sure why all your ruby processes went down, but you should try to replicate it and figure out what is the cause. -- Zed A.
