We are running a group of diskless Sun 3/60's served off of a Sun 3/180 runniing OS 3.4. The problem we have run into involves having a default route in the routing tables and trying to switch YP servers from a diskless client. We first ran into this during booting where the startup of routed came before call to /etc/mount the nfs file systems. The symptom here was that the client would hang here with "yp: server not responding..." messages forever. Commenting out the call to routed solved this problem. We added a static route *after* the nfs mounts and (at least) solved the booting problem. Now the problem is that, if a client's yp server gets slow or is goes down, the client again cannot switch yp servers and starts to hang on the same error message as above. I would be interested in anyone else's input on this problem (we cannot go to 4.0 until the performance problems are solved).
