In NFA, a few of our customers have run into issues with running Flow Forensic reports.
The reports would fail with one of the errors below:
"Error executing Flow Forensics report on host x.x.x.x"
"Query was killed due to a report cancellation"
If you check the <Install_dir>\NFA\Netflow\logs\oursql_*_error.log (which is the log responsible for flow forensics), you may see some errors where it is trying to write to a log that doesn't exist.
"ERROR - NFA CSE could not access [D:\CA\NFA\\Netflow\logs\NFAStorageEngine.log]"
It then fails to write to the log and the NQmySql service stops (and the report fails to execute with one of the errors above).
