Category:	MySQL Cluster: Cluster (NDB) storage engine	Severity:	S1 (Critical)
Version:	4.1.11	OS:	Linux (Linux)
Assigned to:		CPU Architecture:	Any

Description:
when i insert a lot of data in the cluster using the mysql client of an API node, there is no problem. If I make multiple operations like that, I get some errors about duplicate entries

ERROR 1062 at line 7843: Duplicate entry '' for key 65

sometime it gives 

ERROR 1205 at line 141824: Lock wait timeout exceeded; try restarting transaction

and the whole cluster crash

How to repeat:
cluster with 1 admin node
2 api nodes
10 storage nodes.

on api node 1 or 2
lots of insertions with command

cat file1.sql | mysql database_name &
cat file2.sql | mysql database_name &
cat file3.sql | mysql database_name &

ERROR 1062 at line [random_line]: Duplicate entry '' for key 65

(I'm absolutely sure file1.sql, file2.sql and file3.sql 
don't have any duplicate entries.

same process but without parallelism 

cat file1.sql file2.sql file3.sql  | mysql database_name

don't cause this error.

MORE IMPORTANT !

sometimes, the whole cluster crash.

Please attach error and trace files for crash.
