Version:	7.5.1	OS:	Any
Assigned to:		CPU Architecture:	Any

Description:
Create 100 tables and once that is done, start a backup from the mgm node. Immediately, the cluster is crashes with below error:

$ ndb_mgm -e'start backup'
Connected to Management Server at: localhost:1186
Waiting for completed, this may take several minutes
Backup failed
*  3001: Could not start backup
*        Backup aborted due to node failure: Permanent error: Internal error

How to repeat:
1) Start a Cluster.

2) Create 100 tables.

3) Execute:
ndb_mgm -e'start backup'

Documented fix in the NDB 7.5.2 changelog as follows:

    Starting a backup in the ndb_mgm client after creating a large
    number of tables caused a forced shutdown of the cluster.

Closed.
