I cannot reproduce this problem. I tried XEmacs 21.1, XEmacs 21.4,
Emacs 20.7 and Emacs 21.3 with CLISP 2.32. I invoke CLISP with 'clisp
-K full' and that seems work without problems.
What do mean with 'freezes'? 'freeze' as in "Emacs does not respond,
but C-g works" or "Emacs does not respond and I have to kill Emacs
C-g is supposed to work. It would be serious bug in SLIME if it were

What's the value of 'port' here? -------------+
SLIME uses a different/random port for each connection, so it is bit
surprising that you can connect after restarting the server.

Judging from the backtrace, it seems that Emacs can connect, but
apparently CLISP doesn't reply to the first request. The first
request is usually (swank:getpid).
I have no idea what might cause the problem and can only the give the
lame re-compile-everything advice :-) Make sure you have a link to the
metering package as described in swank-clisp.lisp and remove all
byte-compiled .elc files. Add
(setq swank::*redirect-io* nil)
(setq swank::*use-dedicated-output-stream* nil)
(setq swank::*log-events* t)
(setq swank::*sldb-initial-frames* 1)
to your ~/.swank.lisp for better debugging messages. You can also try
to run clisp in a separate xterm, start the swank server with:
and use M-x slime-connect to connect to it.
