This is not the standard behavior. Which version of distcc are you using?
Did you compile it yourself? Any additional patch applied?

Try using distccmon-gnome to monitor the job distribution, it may be more
helpful than top. Also watch the logs for errors. If distribution to
localhost fails, it should generate an error message at some point.
Setting DISTCC_VERBOSE=1 for the client may help.

Which options did you run distccd with on both machines? Didn't you
forget to run distccd on localhost?
