We meet again Jason :-) The number of file handles available is related to the maxusers config parameter. If you wish to alter that without affecting the other table sizes, you can add something like this to your config file .. options "CHILD_MAX=512" options "OPEN_MAX=512" .. numbers should be tweaked as required. However, since the sockets the server has open in the quiescent state are only used to listen on, as soon as a request occurs more will be needed. You have to identify the high-water mark. Personally, with that many domains, I'd be inclined to use multiple boxes to divide the load, michael
