Thanks for the response,So first off, should I keep this dialogue on the hal list or not?And second, if I use the CVS version of dbus is that going to break all the dbus bindings, hal, etc. unless I update those too?  Right now I am using dbus .23.4-7 .  I am just going to try to install the cvs version of dbus anyways .. just tell me what else I should try. And also I have no idea what you mean by using private connections or that they are bounded.  The only resources I have found to learn anything about using hal with dbus is the hal spec and the python examples in the hal package.   On Sat Oct 15 3:26 , 'John (J5) Palmieri' sent: <blockquote style="border-left: 2px solid rgb(245, 245, 245); margin-left: 5px; margin-right: 0px; padding-left: 5px; padding-right: 0px;">So yes. My understanding of how mod_python works is it keeps everything in memory which causes the execution to be faster. It also screws with D-Bus because the bus rules are kept on the bus itself which is out of process and has no idea when your script goes away because apache never gives up the unique bus name. What version of dbus are you using? You can try to remove the signal receiver but to be honest I don't know how well this works. This is an area that needs a little love in the bindings. Also you should most likely move to using private connections though they are not bound yet. It would be great to get feedback from you and I am wondering if you can run the CVS version of D-Bus. I can make those changes tomorrow.
