This may be more a linux issue than Netapp... anyway I'm trying to get Kerberized NFSv3 going between a 810 cluster running 7.0.5 and Fedora Core 5 and 6 clients. I'm following the writeup in Netapp's TR 3481. FC6 works, but the rpc.gssd daemon dies on startup under FC5 with a segmentation fault, and the traceback doesn't seem to shed any light. Any ideas on what I've missed, or how to get something useful out of the core dump?
