I converted the bsd vm to play in VMWare vmplayer.
Ran the same test. CCL segfaulted after about 80 requests.
Could you try with the script I mentioned at
http://clozure.com/pipermail/openmcl-devel/2012-February/013376.html

I guess it doesn't make much difference, but its a relatively easy thing 
to try
