Bug#707960: rpc.gssd segfaults when mounting a nfsv4 volume
Package: nfs-common
Version: 1:1.2.8-2
Followup-For: Bug #707960
Dear Maintainer,
I've also just upgraded to 1.2.8-2 and am experiencing this segfault.
Reverting to 1.2.6-3 does fix the problem. Curiously, I have another
NFSv4 client connected to the same server that did not experience the
problem after upgrade. System info for the failing and working clients
is below. Please let me know if I can do anything to help debug the
issue.
Thanks,
John
