Problems with IndexMemory in config.ini

[Francesco Formizzi]

Hi, I've a problem with the setting of IndexMemory.
This is my config.ini:

[ndbd default]
NoOfReplicas= 2
MaxNoOfConcurrentOperations= 10000
DataMemory= 300M
IndexMemory= 100M
DiskPageBufferMemory=242M
TimeBetweenWatchDogCheck= 30000
datadir= /app/home/mysql/cluster2
#/var/lib/mysql-cluster
MaxNoOfOrderedIndexes= 512
MaxNoOfExecutionThreads=8

#LockPagesInMainMemory=2

[ndb_mgmd default]
DataDir= /var/lib/mysql-cluster

[ndb_mgmd]
Id= 1
HostName= 10.214.130.17
datadir= /app/home/mysql/mgt01/data

[ndbd]
id= 2
HostName= 10.214.130.17
DataDir= /app/home/mysql/ndb01/data

[ndbd]
id= 3
HostName= 10.214.130.17
DataDir= /app/home/mysql/ndb02/data

[mysqld]
id= 4
HostName= 10.214.130.17

[mysqld]
id= 5

[tcp default]
PortNumber= 63132


And this is the result of ALL DUMP 1000:

-- NDB Cluster -- Management Client --
ndb_mgm> ALL DUMP 1000
Connected to Management Server at: localhost:1186

If I calculate the dimension of Index Memory it's not 100M, but only 25M, and I don't know why I've 4 rows for IndexMemory.
This is not correct for me, 'cause I've an "OUT OF MEMORY" when tHe Index Usage is at 25M...

Can you explain me how it's work IndexMemory in mysql Cluster? Can I set 'only 1 row' with 100M of IndexMemory?
