It could be that you just need to set ulimits properly, add enough swap... Think of the load sagenb.org can hold (it's a single machine, you know...), surely it can handle many hundreds of users doing things at the same time.
in our experience 30 people per server, with 12GB of RAM, worked OK. We had a class of over 100 people, sitting in two labs, using 4 different servers. Failing that, get more RAM or run more than one server... > > -- > Jori Mäntysalo > -- You received this message because you are subscribed to the Google Groups "sage-support" group.
