Description hbhuwania93 2021-05-18 19:30:28 UTC 
I am running a linux 5.4 kernel image. 

I am seeing an issue with NFS service crashing randomly. NFS version I am using is 2.3.4 

Apparently the rpc.mountd crashes randomly and dont have a clear picture on what is happening. I tried manually launching this daemon and I see below error traceback:

root@HostName-637562903921812352:/etc# /usr/sbin/rpc.mountd -p 9000 -F -d all

rpc.mountd: Version 2.3.4 starting

rpc.mountd: nfsd_fh: inbuf '* 6 \x8fd3a09e776c46d09e8b8ca1b0e895ec'

rpc.mountd: v4root_create: path '/' flags 0x12407

rpc.mountd: v4root_create: path '/usr' flags 0x10407

rpc.mountd: v4root_create: path '/usr/srvroot' flags 0x10407

*** stack smashing detected ***: <unknown> terminated

Aborted

Any suggestions why NFS is behaving this way?
