Christian,

It looks like you are running hadoop 0.14.
This bug is related to HADOOP-1076 imo.
I recommend to shut down secondary name-node first.
And the restart the main name-node at some point when you are not at 
risk to loose jobs.
You should restart the name-node with -upgrade, otherwise you can hit 
HADOOP-1978,
which is now fixed in 0.14, but I don't know whether you run this patch.
Let me know if it helps.

Thanks,

--Konstantin
