there most be something on your machine, i don't get these with the latest pikefarm. what is your OS/distribution/cpu type/kernel version, don't know what else is interesting.
btw: that gives me the idea that it would be nice if there was a command for pike that would spit out all sorts of debug info. (compile options and detaild about the machine as far as they can be determined (detecting a linux distribution is hard))
