NFS4 Trouble With Kernel 3.8.5-1

We use a workgroup with all homes and data on NFS4. The Arch server works reliable since years and rarley I had to use my "proofed to be stable" spare system, which is one update behind.
I assume the trouble starts with kernel 3.8.5-1. This is what I found in /var/log/errors.log, but nothing like this before April 7

Apr  7 19:44:50 FS rpc.mountd[661]: Caught signal 15, un-registering and exiting.
Apr  8 07:45:48 FS rpc.mountd[635]: Caught signal 15, un-registering and exiting.
Apr  9 08:06:48 FS rpc.mountd[608]: Caught signal 15, un-registering and exiting.
Apr  9 10:52:50 FS rpc.mountd[593]: Caught signal 15, un-registering and exiting.
Apr  9 11:19:15 FS rpc.mountd[2118]: Caught signal 15, un-registering and exiting.
Apr  9 11:58:18 FS rpc.mountd[657]: Caught signal 15, un-registering and exiting.
Apr  9 14:05:25 FS rpc.mountd[1153]: Caught signal 15, un-registering and exiting.

Some of those are due to my restart of the service. But every client is full of this (journalctl -n 500 | grep nfs):

Apr 09 15:39:34 ccandeias kernel: nfs: server 192.168.111.4 OK 

Kernel 3.8.6-1 didn't change anything about it. I also changed and checked all the hardware related.

It causes all client to hang of course. Any ideas?

Beside small troubles which are in the nature of a rolling release I'm a happy Arch user since 2007
