Getting Fatal Error when setting ndb_cluster_connection_pool

Anybody have seen this error before in setting ndb_cluster_connection_pool to a non-default value. I tried 4, 6, 8 but all gave same error.
Interesting thing is, we have 2 mysqld nodes and when i apply this change via mcm, both node gets the change, one node gets running state and 2nd node goes to failed state with this error in the log.
121006 15:14:20 [ERROR] /opt/app/mysql-cluster-advanced-7.2.7-linux2.6-x86_64/bin/mysqld: Incorrect information in file: './mysql/host.frm'
121006 15:14:20 [ERROR] Fatal error: Can't open and lock privilege tables: Got error 157 'Unknown error code' from NDBCLUSTER
Setting the value back to default, gets mysqld running again.
As you can see, i'm running 7.2.7 on Linux 5.8.
