Hi,

I cannot reproduce this. I can shutdown and start multiple times without a problem. I can pull powercable out to have it unsafely shutdown and it is still working ok.

You might want to contact our MySQL Support to check your procedures/config but as for this issue I cannot reproduce it.

I would like to contact if possible your MySQL Support to check our procedures/config because our customer was not satisfied with the response obtained claiming that with the previous version of mysql (mysql-5.6.21 ndb-7.3.7) and operating system (Red Hat Enterprise Linux Server release 6.9 (Santiago))the problem did not arise
