I have a DS3100 which mounts a DS5400's filesystems via NFS. I set
the sticky bit on an executable on the 5400, and then executed it from the
DS3100. The DS3100 immediately panicked and crashed.
This is under Ultrix 4.0. What happened?

I've seen this too, under 3.1 and 4.0. I think Ultrix gets upset if you change the sticky bit on an image which is already in the text table--either a currently running image, or an image which had been run recently and is still in the cache. I thought the BSD documentation had some procedure which somehow forces the image to be flushed from the text table--but I don't have the docs handy to check it. -Dan Riley (riley@theory.tn.cornell.edu, cornell!batcomputer!riley) -Wilson Lab, Cornell University
