This sound even more like the original problem. The symptom was intermitent fails. So if the target server responds quickly enough all is well. But if there's a bit to much trafic or if you stop to scratch it doesn't work. As I said I'd recommend the two patches on kernel.org. > > Is there a way to attach a debugger to the automount process that gets > spawned when the kernel attempts an automount? Nothing that will help in this situation. All the mount/umount is done in userspace by the daemon.
