Errors upgrading from 7.2.7 to 7.2.9 (no replies)

Trying to upgrade an existing environment from MySQL Cluster 7.2.7 to 7.2.9. The cluster will start and all the nodes are active but fails and shutsdown when trying to access tables.

From /data/mysqlcluster/ndb_1_cluster.log I see these errors.
2012-12-12 11:20:18 [MgmtSrvr] ALERT -- Node 10: Forced node shutdown completed. Caused by error 2301: 'Assertion(Internal error, programming error or missing error message, please report a bug). Temporary error, restart node'.

From /data/mysql/error.log I see several of these error messages.
