I've already installed the new version. The size of rmtab went down to 3kb. 
However this does not solve our problems. There are still lots of timeouts 
and the NFS performance is horrible.

Another problem is that if the IO-System is locked the cleanup followed by 
the timeout will nearly certainly fail such that a failover is started that 
will not help much because the same will soon happen on the other machine.

As this all happens in our testing network where we try Ubuntu 12.04 for the 
servers and we do not have such problems with Ubuntu 10.04 we currently 
think that there is something wrong with Ubuntu 12.04.
