Documented bugfix in the NDB-6.3.29b and 7.0.9b changelogs as follows:

        Using a large number of small fragment log files could cause
        NDBCLUSTER to crash while trying to read them during a restart. 
        This issue was first observed with 1024 fragment log files of 
        16 MB each.

Closed.
