A little correction on the connection setting.  My config was reset during maintenence, and was actually set at *infinite* connections, but Xitami ceased to respond at about 11 connections on my box.  The denial of service condition appears to be an overloaded piece of code in a library/core module.  It appears to be max-ed out when Xitami stops checking for new session requests.  However, what puzzles me is *why* the service is halting checks when it has no connection limit set.
