Data nodes alway shutdown, unable to startup (2 replies)

Hi,

I have a cluster with 2 data nodes plus a management node and it works for initialization but not for time to import data, migration engine from MyISAM to NDB and some time during cluster running. I try to restart data node as recommendation from error log but both alway failed (cannot predicted somtime able to start but many not - -'), especialy when configured data memory more than > 2 GB. They so many error logs alway reported "Internal program error, please report a bug" Today, i'm not so sure mysql cluster is ready for production. Please, How can i build my cluster stable?
