Status:	Closed	Impact on me:	None
Category:	MySQL Cluster: Cluster (NDB) storage engine	Severity:	S2 (Serious)
Version:	mysql-5.1-telco-6.3	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
Internal buffer overrun cause data node to stop.

How to repeat:
Not a test case, but this is the error report:

Status: Temporary error, restart node 
Message: Pointer too large (Internal error, programming error or missing error message, please report a bug) 
Error: 2306 
Error data: dblqh/DblqhMain.cpp 
Error object: DBLQH (Line: 3656) 0x0000000a 
Program: ndbd 
Pid: 27865 
Trace: /l**************/ndb_3_trace.log.5 
Version: mysql-5.1.47 ndb-6.3.35-GA 

Suggested fix:
Already fixed in MySQL Cluster 7.0 with a rewrite of code around the failure, but this can't go into 6.3.

It's not an overrun :)

A patch for this bug has been committed. After review, it may
be pushed to the relevant source trees for release in the next
version. You can access the patch from:
