DOCS: If a LCP got a transient error (in this case 1217) it would crash
  data-node. This patch solves this by retrying operation 10 times with
  100ms delay.

Documented bugfix in the NDB-7.0.20 and 7.1.9 changelogs, as follows:

        Transient errors during a local checkpoint were not retried,
        leading to a crash of the data node. Now when such errors occur,
        they are retried up to 10 times if necessary.
