Package: linux-image-amd64 Version: 4.19+105 During logrotation of files residing on NFS share the NFS client report error "nfs4_reclaim_open_state: unhandled error -521". After that all the listings of the directory were hanging on IO. Only the subdirectory is affected, files and other directories out of the affected path are accessible with no issues. Mounted with: data.isil01.domain:/locofwd/fwd01 on /var/log/remotelogs type nfs4 (rw,nosuid,nodev,noexec,relatime,vers=4.0,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.x.y.z,local_lock=none,addr=10.a.b.c) Storage does not support NFS4.1, thus vers=4 used.
