Hi Hans,
I have update your patch to my web server(its hunchentoot version is 1.1.1). If I found some error output,I'll send them to this mail list.
My site use a flexi-stream with cp936 patched (https://github.com/jingtaozf/flexi-streams). And the site use utf-8 as default encoding but some browser send us cp936 characters sometimes.
With Best Regards. jingtao.
https://github.com/edicl/hunchentoot/commit/f4a3bbd5a915f83c42ff2351978f2e34... fixes your problem? If so, you should see a message on the console when logging an error failed. Please share that message. My suspicion is that the problem is related to character encoding problems (i.e. Hunchentoot tries to write characters that cannot be encoded in the external format of the error log stream), but at this point, this is just a guess. The error message will help.
Thanks, Hans
