error 2341

I'm running cluster with 12 datanodes and got an unexpeced error.
First, node 4 was forced to shut down, then all other nodes followed.

Why does the complete cluster shut down, if just one node fails? What's the use of redundancy, if the cluster can't cope with a lost node?

How can I collect log data to report a bug having Debian Linux data nodes and Windows MySQL and management nodes?



The error happened after:

MySQL error (1297): Got temporary error 488 'Too many active scans' from NDBCLUSTER
