Those symptoms don't remind me of any bug I know about right off hand.
You might try updating your CCL, though. You appear to be using the original 1.3 release binary, and I know that there have been important bug fixes to the 1.3 branch since release.
Thanks for the quick response. I've updated from Subversion and rebuilt CCL to 1.3-r12755M. Hopefully that will fix the problem.

I finally managed to get a backtrace on this problem. I've reduced the deployment down to the latest Clozure running on 64-bit Linux with Hunchentoot 1.0.0 hosting only static files. These files are generated from Dreamweaver, so I put them in a directory named 'static' and configure Hunchentoot like this: (push (hunchentoot:create-folder-dispatcher-and-handler "/" (make-pathname :directory (concatenate 'string *web-path* "/static"))) hunchentoot:*dispatch-table*) ;; (register-static-file "crossdomain.xml") (defun display-home-page () "Display the home page." (hunchentoot:redirect "/index.html")) (push (hunchentoot:create-regex-dispatcher "^/$" 'display-home-page) hunchentoot:*dispatch-table*) I start the server like this: (defparameter hunchentoot:*message-log-pathname* "/tmp/hunchentoot-message.log") (defparameter hunchentoot:*access-log-pathname* "/tmp/hunchentoot-access.log") (defparameter *web-acceptor* (make-instance 'hunchentoot:acceptor :port 8080)) (hunchentoot:start *web-acceptor*) This works for a random amount of time, then I get errors like this in the Hunchentoot message log: [2009-09-13 15:35:16 [ERROR]] Error while processing connection: Input timeout o n #<BASIC-TCP-STREAM ISO-8859-1 (SOCKET/13) #x300041C5834D> [2009-09-13 15:35:16 [ERROR]] Error while processing connection: Input timeout o n #<BASIC-TCP-STREAM ISO-8859-1 (SOCKET/6) #x300041C5E9AD> [2009-09-13 15:35:16 [ERROR]] Error while processing connection: Input timeout o n #<BASIC-TCP-STREAM ISO-8859-1 (SOCKET/14) #x300041C599AD> And this in the output log (I'm running via detachtty, if that makes a difference): Welcome to Clozure Common Lisp Version 1.3-r12755M (LinuxX8664)! ?

The full backtrace is available at http://www.softwarematters.org/ccl64-dribble.gz . Is this a Clozure or Hunchentoot issue? Thanks, Patrick
