Ultrix 4.0 and automount

[Kenstir]

I am running Ultrix 4.0 on a DECstation 3000 as a YP client.
Automount seemed to cause my machine to get into an infamous (and infinite)
"NFS server pid666@/u not responding still trying" wait.
Are there any patches to 4.0 automount yet, or is it simply not
advisable to run it, especially under YP?

Thanks for any help...
