I can't increase "DataMemory" in configuration parameters.

[Andy Kim]

Hello.

I'm testing the mysql clusters.

the version is ndb-6.15 (mysql-cluster-gpl-6.2.15-linux-i686-glibc23.tgz)

1 management node
2 data nodes


I can't increase DataMemory over 6GB.

I teasted it for 2 cases.

first, when I increased 7GB and started Data Node, i got a error messages.

ndb_mgm> Node 2: Forced node shutdown completed. Occured during startphase 0. Caused by error 2327: 'Memory allocation failure, please decrease some configuration parameters(Configuration error). Permanent error, external action needed'

second, when I increased 10GB and started Data Node, i got a error messages.

ndb_mgm> Node 2: Forced node shutdown completed. Occured during startphase 0. Initiated by signal 11. Caused by error 6000: 'Error OS signal received(Internal error, programming error or missing error message, please report a bug). Temporary error, restart node'.

is 6GB a data memory limitation ? no way !!! please help me !!

my sever spec is 4GB RAM, 160GB HDD, Cent OS 5.2 64bit.

and

my configuration is ...

[ndbd default]
NoOfReplicas=2
DataMemory=6GB # I can't increase this value.
IndexMemory=1024M

TCP/IP options:
[tcp default]
portnumber=2202

[ndb_mgmd]
hostname=node1
datadir=/var/lib/mysql-cluster

[ndbd]
hostname=node2
datadir=/usr/local/mysql/ndbdata

[ndbd]
hostname=node3
datadir=/usr/local/mysql/ndbdata

# SQL node options:
[mysqld]
