I have also seen this issue but fixed it by reducing the memory used as
I was on a test system.

Subject: nodes ignoring MemReportFrequency setting when 80% reached
Hi all,
I've just finished my test to confirm this. I loaded up some data and
"all dump 1000" reported 79% data usage. In my ndb_mgmd config, I
specified MemReportFrequency=600 (every 10 minutes). As long as data
usage stayed below 80%, the usage was reported properly every 10 minutes
in the ndb_mgm console and thru the MGM API.
But as soon as that 1 record was inserted to push the usage to 80.00%,
the report frequency suddenly changed to every second for all 4 ndbd
nodes!
My mgm console was now being flooded with the reports as is the MGM API.
I don't see anything in the docs that state this is normal behavior. Bug
possibly?
Thanks,
Matthew
