Corruption of the database on port 3307.
The \CA\NFA\Netflow\data\oursql*.log file on your Harvesters shows the message below:
INFO - If you want more detailed logging for NFA CSE, please create the log file [E:\CA\NFA\\Netflow\logs\NFAStorageEngine.log] (and on Linux ensure that it is writable by the NFA user)
After creating that log file, then recycling the Netqos NQMysql Service, and running the report again, the problem still occurred and had the log messages like below:
