Still can't get 2NN working

Mayuran Yogarajah
A few weeks ago I set up the secondary namenode to run on a different
as follows:

- on the NN I put the host of the 2NN server inside the slaves file
- on the 2NN I added the following to the hadoop-site.xml file

    The address and the base port where the dfs namenode web ui will
listen on.
    If the port is 0 then the server will start on a free port.

I've been seeing this error in the 2NN log:
2009-10-20 20:41:15,536 INFO org.apache.hadoop.dfs.NameNode.Secondary:

2009-10-20 20:41:15,540 ERROR org.apache.hadoop.dfs.NameNode.Secondary:
Exception in doCheckpoint:
2009-10-20 20:41:15,540 ERROR org.apache.hadoop.dfs.NameNode.Secondary:

I'm stuck at this point and have no idea how to fix this :/  Does anyone
have any ideas?
I'm using Hadoop 0.18.3 btw..
