Description:
I have a 8 NDBD node (8machines) 2replica setup. Each node with 6gb memory.
I proceeded to go from nodeid 18 through to 11;
X stop (and wait for it to stop)
X# ndbd (and wait for it to start)
Where X is 18, 17, 16, 15, 14, 13, 12, 11*
*11: This was the last node (and was 'Master' in 'show' output.), and triggered the full crash.

See http://lists.mysql.com/cluster/3273 for Jonas Oreland's comment.

How to repeat:
See above, It may have something to do with query load on the cluster, or the amount of data in a running cluster.

The problem is that the master takeover prints so much in cluster log
so that sendbuffer gets full...

solution: timeslice or decrease printouts
