[slime-devel] Lisp connection closed unexpectedly

Recently when I tried to start slime, most of the time it throw a error message: Connecting to Swank on port 45744.. [2 times] Lisp connection closed unexpectedly: connection broken by remote peer in *inferior-lisp* it shows: ;; Swank started at port: 45744. 45744 * ;; swank:close-connection: end of file on #<SB-SYS:FD-STREAM for "a socket" {B1593F1}> But I run slime again and don't create an additional inferior lisp, it works very well. I don't know why and can not get any debug information about it. I used Emacs 23.1.1, SLIME 2009-12-03, SBCL 1.0.31-2, my inferior-lisp-program is "/home/plato/clbuild/clbuild --implementation sbcl lisp" Thank you in advance!
