Package: nfs-common
Version: 1:1.3.4-6
Severity: normal

Dear Maintainer,

Error: NFS: __nfs4_reclaim_open_state: Reclaim lock failed!

* What led to the situation?
  Migrate NFS server from debian 9 to debian 11.
* What exactly did you do (or didn't do) that was effective (or ineffective)?
  Apparently everything works correctly with few users, when I increase to more than 20 or 30 users the blockages begin in the machines.
* What was the result of this action?
 Error on clients: NFS: __nfs4_reclaim_open_state: Reclaim lock failed!
 The clients are blocked and the client machines cannot be used.
* What results did you expect instead?
 That the server will work without problems with the more than 50 users.

Hi

[This reply and bug closer is sent for doing BTS maintenance for
src:nfs-utils bugs]

This bug was reported against a very old nfs-utils version without much
followups/triaging itself.

If you can reproduce it with the current version in unstable/testing or
stable at least, please reopen the bug,
https://www.debian.org/Bugs/server-control for details.

Regards,
Salvatore
