ssl support

I am currently writing a web application using Hunchentoot; but it seems that there is a problem with its ssl support (using easy-ssl-acceptor): for some unknow reason for me, sbcl, the commom lisp implementation that I use, grows its memory whitout limit when I make tests with ab. I have tested with hunchentoot:easy-acceptor and this problem with the memory does not occur. Does anyone of you guys had seen this behavior?
