NFSv4: cannot allocate memory errors when moving files

When I move a directory on an NFS client to another location then I can't create a file on that other location anymore:

[willem@venus ~]$ mkdir test
[willem@venus ~]$ mv test /pub/music
[willem@venus ~]$ cd /pub/music/test
[willem@venus test]$ touch a
^C

the touch command does nothing on the nfs client (it hangs, so I Ctrl-C).

When I logon to the NFS server the following happens:

[willem@titan W]$ cd /pub/music/test
[willem@titan test]$ touch x
touch: cannot touch 'x': Cannot allocate memory
[willem@titan test]$

This only happens if the mv command moves the directory over different NFS mount points.

I have an older arch NFS server with a 3 months old arch install, and this issue does not occur there.

If I mount the nfs client directories with nfsvers=3 in my fstab then it also does not occur, so it seems to be broken in a recent update in NFS4
