Hi,
I think it tells you what the problem is:
Got error 902 'Out of memory in Ndb Kernel, ordered index data (increase
DataMemo
ry)' from ndbcluster
I therefore suggest you increase DataMemory in config.ini.
I guess that it was creating a tempoary table during a query and hit
this limit... but there could be other explanations.
There are commands to see how much DataMemory and IndexMemory are free
on nodes which you can search the list for details on. Clearly its not
disk space but allocated RAM that you have run out of here.
Best wishes,
Alex
