Hi!
The recent 2.35 patch unfortunately introduces the possibility for another bug: If you've configured multiple mod_lisp instances in one Apache then a socket which has served one Lisp image may be re-used for a different Lisp image. This shouldn't happen, of course.
The attached patch tries to fix that. It stores the server ip address and port together with the socket and only re-uses the socket if the former values haven't changed.
Cheers, Edi.
