In your case you always have it with sunrpc, so i think you got more problem with hardened configuration and nfs interaction.

If nfs didn't think of a scenario that trying to assign/access memory could fail, it might just crash dump like that, and hardened kernel can do that kind of stuff : denied memory access or write...
I would look at hardened options to see if i could be less strict with nfs handling ; try search a bit, such issue should be commonly seen (if it's that of course).
