Any tips on optimizing usage of Virtual Hosts, I narrowed down the problem a bit. I can have 500 users running without any memory problems on the server if I set them all up under localhost/userXXX but as soon as I start assigning virtual hosts to each user, I crash at about a 100. Same problem 1GB ram avaiable but server crashes at like 350MB, any ideas?
