How to repeat:
start a cluster with 
MemReportFrequency=10

ndb_mgm> 
all report mem

start a cluster without MemReportFrequency

ndb_mgm>
all report mem

Suggested fix:
print it only once in case MemReport.. is set.

Documented bugfix in the NDB-6.3.33. 7.0.14, and 7.1.2 changelogs, as follows:

        When the MemReportFrequency configuration parameter was set in
        config.ini, the ndb_mgm client REPORT MEMORYUSAGE command
        printed its output multiple times.
