Problem with simple cluster?

I seem to be having a problem with a very simple four-node cluster. Apparently the ndb_mgmd host REALLY does not like the second DBD host. Although the first DBD host can connect and the MySQL host can as well.
What actually seems to happen is that when I run ndbd they all connect up fine and everything is happy. Start mysqld on the first data node, everything's great. Then when I goto start mysqld on the second one it borks and dies. It actually seems to be rejected by the mgmd node, although I can't figure out why. In fact, I can even start it first, and the same thing will happen.
Here's my setup (All running 4.1.12, compiled with same opts, etc):
10.1.1.10: FBSD 5.3-Stable - Management Node
10.1.1.11: FBSD 5.3-Release - Data Node 1
10.1.1.12: FBSD 5.3-Release - Data Node 2
10.1.1.13: FBSD 4.9-Release - Mysql Node
cluster.ini file:
[ndbd default]
NoOfReplicas=2
DataMemory=80M
IndexMemory=52M
MaxNoOfConcurrentOperations=10000
MaxNoOfOrderedIndexes=512
TimeBetweenWatchDogCheck=30000
[tcp default]
PortNumber=2202
[ndb_mgmd]
Id=1
HostName=10.1.1.10
[ndbd]
Id=2
HostName=10.1.1.11
[ndbd]
Id=3
HostName=10.1.1.12
[mysqld]
Id=4
HostName=10.1.1.13
------
my.cnf file (on data1/2, mysql):
[mysqld]
ndbcluster
ndb-connectstring=10.1.1.10
datadir=/var/db/mysql/data
[mysql_cluster]
ndb-connectstring=10.1.1.10

Logfile of debug level output from mgmd host (Didn't bother connecting up the mysql node on this one):
