Hi Dennis, Your description of this problem is a bit unclear to me. I think you're talking about about more than one issue. Firstly the multiplexing of mounts is likely referring to the kernel sunrpc implementation which is not part of the autofs code. There certainly is a problem there that's been discussed many times. There are a couple of patches around but I don't believe any are ready for general use. This would allow you to mount that many mounts but, with a 2.4 kernel and the more-unnamed patch such as is in RedHat kernels, you will run out of unnamed devices at just over 1200. The limitation on unnamed devices has been removed in 2.6. The second thing is that you may be using the multi-mount (auto.net) type mounts from these servers whereby accessing it mounts all the servers exports. Lazy mount/umount for multi-mounts is not done yet. I was this very morning thinking about the way in which this will be implemented. Unfortunately, when this is done it will require the reworked direct mount functionality that is well underway now. In any case I'm not sure that this will actually play well with the aggressive directory tree scanning of file managers found in KDE and Gnome. We'll just have to see.
