Many syscalls won't work correctly if you change that (select e.g.). If you need to use more than 1024 open file descriptors in an application, you have to explicitely support it, as POSIX does not allow you to do sth like that with select and friends. Poll can though. epoll too. I also have a hard time understanding why having 1000+ virtualhosts in apache would create such problems (except if you listen of 1000+ different ports btw, but I don't think it would be a very clever setup anyway :]) Cheers, -- ·O· Pierre Habouzit ··O madcoder@debian.org OOO http://www.madism.org
