I am aware of the thread you are referring to; I am referring to something different, at least I believe so! > How much memory do you allocate to the virtual server?

The machine does not halt - you can usually still log in. His point of view is that the current issue is not networking-related, but rather that the various notebooks opening up are creating so many processes that the system is overtaxed. What I am wondering is if anyone knows how quickly a) multiple logins to a notebook might do that or b) interact processes might do that (do the objects get cached, for instance?) or c) people forgetting to log out and perhaps leaving a notebook running might do that or d) something else I can't think of might do that. Sysadmin knows about VMs but not so much about internals of Sage, so he isn't sure if it's simply people logging in and then not logging out while the notebook is still active, or if it could be something else. I understand that to some extent there is a lot of uncertainty as to how efficiently the notebook works, but I know so little about how it works (and about interact) that I'm asking the stupid questions, in case one of them turns out to have part of the answer.
