Description:
I am using mysql-5.1.27-ndb-6.3.17 in real service.
recently, shorking accident was occured.
I run "show tables" mysql command.
and thus, Existing tables was dropped suddenly.
How to repeat:
1.
Use this config.ini in testing.([NDBD DEFAULT] part must same this config.ini)

---------------------------------
2.
firstly, this script run.
cat create1.sh
---------------------------------

}
run(){

echo "creating table of $1"

while [ $i -lt $2 ]
do
echo $i
create $i $1
if [ -n "$RESULT" ]; then
echo $RESULT
exit
fi
i=`expr $i + 1`
done
}
# don't change dbname. use dbname written in this script
run db_aaaa_aaa 79
run db_bbbb_bbbb 28
run db_cccccc 13
------------------------------------------------
#./create1.sh
and thus, confirm table created.
# mysql -uroot
# use db_bbbb_bbbb;
# show tables;
mysql> show tables;

}

run db_ppp 46
-----------------------------------------------

and thus, check tables created by create1.sh
# mysql -uroot

upper query taked long time.
but, shorking problem is next.
mysql> show tables;
Empty set (0.00 sec)
tables created create1.sh, all droped.
