Title:
  connection to a nfs volume from a client freezes the whole server
  randomly

Status in nfs-utils package in Ubuntu:
  Confirmed

Bug description:
  This behaviour occured since the beginning of july. First I tried
  Ubuntu 20.04 on my notebook and I experienced this problem. Therefore
  I thought, that ubunut 20.04 nfs client and 18.04 nfs server where
  incompatible in some kind. Then I reinstalled Ubuntu 18.04 on my
  notebook. But the problem still exists.

  I'm running kernel 5.3 on both client and server. I use the package
  autofs for mounting volumes.

  Because the system crashes, I could not find any logs.

  Any hint what I should do, finding this error. Thank you!
