looks like some real bug or problem, but it is not really possible to
diagnose it further without seeing a strack trace.  Can you

and then type :b to see a backtrace of the process that has crashed?

are about, but I suspect that they are from junk typed into the repl
or bugs in your program.

The messages below are harmless, and many of them do not occur with
the development version of Hunchentoot and usocket.

I do not think that you have a configuration problem, but I'd
recommend that you upgrade to a recent version of Hunchentoot and its
dependencies from Subversion (http://bknr.net/svn/ediware) before
investigating the problem further.
