I have the same problems, but I can add extra information. I have two systems (DECsystem5000/200's) that are clustered together. They run Ultrix 4.0. They share the /usr file system, but they have their own private / and /var . Their kernels are identical. In the original set-up, system ONE did the printing via LAT, and system TWO printed remote on ONE. Both system accepted LAT sessions. Then system ONE started crashing with the problems described in the referenced articles. So I disabled LAT on ONE, and had system TWO printing directly via LAT. This way I had two systems running, though only one of them supported LAT. Then I patched the kernel of ONE, after which it could handle LAT again. But now it exposes the printer problems. System TWO, with an un-patched kernel, still runs, accepts LAT connections and prints via LAT. If the problem were in the network or in the terminal servers --we have DECserver200's-- I would have expected both systems to suffer. If it were in the (Ultrix-) software, I would also expect both systems to suffer equally. Both systems are doing well on TCP/IP and NFS, so the network hardware seems reliable. Wonderful, isn't it?
